One-Sample Hypothesis Testing Cases, health and medicine homework help
The purpose of this assignment is to develop students' abilities to combine the knowledge of descriptive statistics covered in Weeks 1 and 2 and one-sample hypothesis testing to make managerial decisions. In this assignment, students will learn how statistical analysis is used in predicting an election winner in the first case. In the second case, students will conduct a hypothesis test to decide whether or not a shipping plan will be profitable. Assignment Steps Resources: Microsoft Excel®, Case Study Scenarios, SpeedX Payment Times Develop a 700- to 1,050-word statistical analysis based on the Case Study Scenarios and SpeedX Payment Times. Include answers to the following: Case 1: Election Results Use 0.10 as the significance level (α).Conduct a one-sample hypothesis test to determine if the networks should announce at 8:01 P.M. the Republican candidate George W. Bush will win the state. Case 2: SpeedXUse 0.10 and the significance level (α).Conduct a one-sample hypothesis test and determine if you can convince the CFO to conclude the plan will be profitable.

Colorado State University Cars Critical Thinking Paper
Option #1: Critical Thinking: Cars
An expert who works for a car magazine obtained random data (rounded to the nearest thousand) among two categories of used or new cars: Domestic Foreign
The expert would like to understand sales based on list price (rounded to the nearest thousand dollars), sale price (rounded to the nearest thousand dollars), and number of days it takes to sell each car. The complete data set is in the file named Cars.
Managerial Report
Prepare a report (see below) that summarizes your assessment of the nature of the car market. Be sure to include the following seven items in your report.
Calculate descriptive statistics (mean, median, range, standard deviation, and coefficient of variation) to summarize each of the three variables for the all Domestic cars.
Use z-scores to determine if there any outliers in the data set for any of the three variables. If there are any outliers in any category, please list them and state for which category they are an outlier.
If a result is an outlier, state whether it is below or above the mean.
How can one use the above descriptive statistics to understand the Domestic car market better?
Could there be any other descriptive statistics that can help one understand the Domestic car market better?
Descriptive statistics (mean, median, range, standard deviation, and coefficient of variation) to summarize each of the three variables for the all Foreign cars.
Use z-scores to determine if there any outliers in the data set for any of the three variables.
If there are any outliers in any category, please list them and state for which category they are an outlier.
If a result is an outlier, state whether it is below or above the mean.
How can one use the above descriptive statistics to understand the Foreign car market better?
Could there be any other descriptive statistic that can help one understand the Foreign car market better?
Compare your summary results from #1 and #2. Discuss any specific statistical results that would help the car expert understand the two-car markets.
Develop a 98% confidence interval estimate of the population mean sales price and population mean number of days to sell for Domestic cars. What is the margin of error?
Interpret what each confidence intervals means. How can both confidence intervals provide useful car sales information?
What other confidence interval would you choose to compute to obtain more information related to Domestic car sales? Explain why.
What happens to the confidence interval as the level of confidence is increased?
Develop a 98% confidence interval estimate of the population mean sales price and population mean number of days to sell for Foreign cars. What is the margin of error?
Interpret what each confidence intervals means. How can both confidence intervals provide useful car sales information?
What other confidence interval would you choose to compute to obtain more information related to Domestic car sales? Explain why.
Assume the car expert requested estimates of the mean number of days to sell for the Domestic cars with a margin of error of seven days and the mean selling price of foreign cars with a margin of error of eight days.
Using 98% confidence, how large should the sample sizes be for each one?
How could the sample size formula be useful in understanding both types of car businesses? What are some advantages of a larger sample size?
Suppose a Domestic car has a list price of $30,000 and a Foreign car has a list price of $30,000. What is your estimate of the final selling price (based on the percent difference for the sale and list price) and number of days required to sell each of these cars?
How would these two estimates be useful in this application?
Write a report that adheres to the formatting and APA expectations outlined on the CSU Global Writing Center (Links to an external site.). As with all written assignments at CSU Global, you should have in-text citations and a reference page.
Submit your Excel file in addition to your report.

Gottfried von Leibniz “And the invention of” Calculus
Gottfried Wilhelm Leibniz was a genius in many fields including law, religion, statecraft, history, literature, logic, metaphysics, and speculative philosophy. Leibniz, born on July 1, 1646, applied mathematical reasoning to the phenomena of the physical universe. He imagined calculus and combinatorial analysis.
