Cigarette Smokers Make Lower College Grades Than Nonsmokers, discussion help
- DQ 1 Consider the following news headline, "Cigarette Smokers Make Lower College Grades Than Nonsmokers." The article goes on to say that researchers at a university collected information on the rate of cigarette smoking (total number of cigarettes smoked in a one-month period) and the college student's current GPA for completed college courses. They found that those with higher levels of cigarette use had lower GPAs, and vice versa. What can you rightfully conclude from this? Why? Be specific about what this kind of information may indicate and mean.DQ 2A pharmaceutical company conducts a study to evaluate the relationship between length of time taking drug X and size of tumor. They enlist 2,400 patients with the same type of benign tumor who have been on drug X for varying lengths of time (measured in days). They find that the longer the patient is on the drug, the smaller the patient’s tumor size (measured in volume). In fact, they report the results as r(2398) = -.21, with significance of p < .0001. What is your initial perception of this information? What are other ways, beyond looking at the p-value alone, you could use to try to interpret what this outcome of r(2398) = -.21 tells us about the relationship between length of time taking drug X and the size of the tumor? Support your responses.

SNHU Regional Average Market Price of Places of Residence Statistics Report
In this project, you will demonstrate your mastery of the following competency:
Apply statistical techniques to address research problems
Perform hypothesis testing to address an authentic problem
Overview
In this project, you will apply inference methods for means to test your hypotheses about the housing sales market for a region of the United States. You will use appropriate sampling and statistical methods.
Scenario
You have been hired by your regional real estate company to determine if your region’s housing prices and housing square footage are significantly different from those of the national market. The regional sales director has three questions that they want to see addressed in the report:
Are housing prices in your regional market higher than the national market average?
Is the square footage for homes in your region different than the average square footage for homes in the national market?
For your region, what is the range of values for the 95% confidence interval of square footage for homes in your market?
You are given a real estate data set that has houses listed for every county in the United States. In addition, you have been given national statistics and graphs that show the national averages for housing prices and square footage. Your job is to analyze the data, complete the statistical analyses, and provide a report to the regional sales director. You will do so by completing the Project Two Template located in the What to Submit area below.

Georgia Military College The Empirical Rule Exam Practice
For the past ten years, grades on the final exam in Mr. Statman’s statistic course have been normally distributed with a mean of µ = 75 and a standard deviation of σ = 15. Mr. Statman has a current class with 50 students. Let us predict some outcomes on the final exam for that class.a) Draw a normal distribution. Include the mean and two standard deviations. Complete this sentence using the Empirical Rule: Approximately, 95% of students will score between _____ and ______ on the final exam.b) Shade in the A range (90 and above) on your distribution in part a. Find the probability that a randomly selected student makes an A on Mr. Statman’s final exam. How many of the 50 students do we expect to make an A?c) Suppose that we randomly select 5 students from the class and AVERAGE their final exam scores. The Central Limit Theorem indicate that the average of the 5 students will fall somewhere in a Normal Distribution with = _______ and = _______. Complete this sentence using the Empirical Rule: Approximately, 95% of the time the average of 5 random students will fall between _____ and ______ on the final exam. d) Find the probability that the average of the 5 students is an A average (90 and above).e) Let’s do the same thing that we did in parts c and d, except for the entire class of 50. The Central Limit Theorem indicate that the average of the 50 students will fall somewhere in a Normal Distribution with = _______ and = _______. Complete this sentence using the Empirical Rule: Approximately, 95% of the time the average of 50 random students will fall between _____ and ______ on the final exam.f) Find the probability that the average of the 50 students is an A average (90 and above).g) Find the following probabilities (you redoing parts b, d, and f, but with a C instead of an A) : A) P(a randomly selected student makes a C on the final exam) = ______ B) P(a sample of 5 randomly selected students make a C average of the final exam) = _____ C) P(the class average of all 50 students will be a C average)h) Discuss what you have learned from this exercise.Respond too two peer

Cigarette Smokers Make Lower College Grades Than Nonsmokers, discussion help
- DQ 1 Consider the following news headline, "Cigarette Smokers Make Lower College Grades Than Nonsmokers." The article goes on to say that researchers at a university collected information on the rate of cigarette smoking (total number of cigarettes smoked in a one-month period) and the college student's current GPA for completed college courses. They found that those with higher levels of cigarette use had lower GPAs, and vice versa. What can you rightfully conclude from this? Why? Be specific about what this kind of information may indicate and mean.DQ 2A pharmaceutical company conducts a study to evaluate the relationship between length of time taking drug X and size of tumor. They enlist 2,400 patients with the same type of benign tumor who have been on drug X for varying lengths of time (measured in days). They find that the longer the patient is on the drug, the smaller the patient’s tumor size (measured in volume). In fact, they report the results as r(2398) = -.21, with significance of p < .0001. What is your initial perception of this information? What are other ways, beyond looking at the p-value alone, you could use to try to interpret what this outcome of r(2398) = -.21 tells us about the relationship between length of time taking drug X and the size of the tumor?

SNHU Regional Average Market Price of Places of Residence Statistics Report
In this project, you will demonstrate your mastery of the following competency:
Apply statistical techniques to address research problems
Perform hypothesis testing to address an authentic problem
Overview
In this project, you will apply inference methods for means to test your hypotheses about the housing sales market for a region of the United States. You will use appropriate sampling and statistical methods.
Scenario
You have been hired by your regional real estate company to determine if your region’s housing prices and housing square footage are significantly different from those of the national market. The regional sales director has three questions that they want to see addressed in the report:
Are housing prices in your regional market higher than the national market average?
Is the square footage for homes in your region different than the average square footage for homes in the national market?
For your region, what is the range of values for the 95% confidence interval of square footage for homes in your market?
You are given a real estate data set that has houses listed for every county in the United States. In addition, you have been given national statistics and graphs that show the national averages for housing prices and square footage. Your job is to analyze the data, complete the statistical analyses, and provide a report to the regional sales director. You will do so by completing the Project Two Template located in the What to Submit area below.
Directions
Introduction
Purpose: What was the purpose of your analysis, and what is your approach?
Define a random sample and two hypotheses (means) to analyze.
Sample: Define your sample. Take a random sample of 100 observations for your region.
Describe what is included in your sample (i.e., states, region, years or months).
Questions and type of test: For your selected sample, define two hypothesis questions and the appropriate type of test hypothesis for each. Address the following for each hypothesis:
Describe the population parameter for the variable you are analyzing.
Describe your hypothesis in your own words.
Describe the inference test you will use.
Identify the test statistic.
Level of confidence: Discuss how you will use estimation and conference intervals to help you solve the problem.
1-Tail Test
Hypothesis: Define your hypothesis.
Define the population parameter.
Write null (Ho) and alternative (Ha) hypotheses.
Specify your significance level.
Data analysis: Analyze the data and confirm assumptions have not been violated to complete this hypothesis test.
Summarize your sample data using appropriate graphical displays and summary statistics.
Provide at least one histogram of your sample data.
In a table, provide summary statistics including sample size, mean, median, and standard deviation.
Summarize your sample data, describing the center, spread, and shape in comparison to the national information.
Check the conditions.
Determine if the normal condition has been met.
Determine if there are any other conditions that you should check and whether they have been met.
Hypothesis test calculations: Complete hypothesis test calculations, providing the appropriate statistics and graphs.
Calculate the hypothesis statistics.
Determine the appropriate test statistic (t).
Calculate the probability (p value).
Interpretation: Interpret your hypothesis test results using the p value method to reject or not reject the null hypothesis.
Relate the p value and significance level.
Make the correct decision (reject or fail to reject).
Provide a conclusion in the context of your hypothesis.

Georgia Military College The Empirical Rule Exam Practice
For the past ten years, grades on the final exam in Mr. Statman’s statistic course have been normally distributed with a mean of µ = 75 and a standard deviation of σ = 15. Mr. Statman has a current class with 50 students. Let us predict some outcomes on the final exam for that class.a) Draw a normal distribution. Include the mean and two standard deviations. Complete this sentence using the Empirical Rule: Approximately, 95% of students will score between _____ and ______ on the final exam.b) Shade in the A range (90 and above) on your distribution in part a. Find the probability that a randomly selected student makes an A on Mr. Statman’s final exam. How many of the 50 students do we expect to make an A?c) Suppose that we randomly select 5 students from the class and AVERAGE their final exam scores. The Central Limit Theorem indicate that the average of the 5 students will fall somewhere in a Normal Distribution with = _______ and = _______. Complete this sentence using the Empirical Rule: Approximately, 95% of the time the average of 5 random students will fall between _____ and ______ on the final exam. d) Find the probability that the average of the 5 students is an A average (90 and above).e) Let’s do the same thing that we did in parts c and d, except for the entire class of 50. The Central Limit Theorem indicate that the average of the 50 students will fall somewhere in a Normal Distribution with = _______ and = _______. Complete this sentence using the Empirical Rule: Approximately, 95% of the time the average of 50 random students will fall between _____ and ______ on the final exam.f) Find the probability that the average of the 50 students is an A average (90 and above).g) Find the following probabilities (you redoing parts b, d, and f, but with a C instead of an A) : A) P(a randomly selected student makes a C on the final exam) = ______ B) P(a sample of 5 randomly selected students make a C average of the final exam) = _____ C) P(the class average of all 50 students will be a C average)h) Discuss what you have learned from this exercise.Respond too two peer
