Phase 3 Hypothesis testing
This week you will begin working on Phase 3 of your course project.
Using the same data set and variables for your selected topic that you
used for phases 1 and 2, add the following information to your
analysis:Discuss the process for hypothesis testing.
Explain the 8 steps of hypothesis testingWhen performing the 8 steps for hypothesis testing, which method do you prefer; P-Value method or Critical Value method? Why?Perform the hypothesis test. (Salaries):
Claim: The average salary for all
jobs in Minnesota is less than $65,000. Test the claim using α = 0.05
and assume your data is normally distributed and σ is unknown.
Based on your selected topic, perform and document the following steps:
Write the null and alternative hypothesis symbolically and identify which hypothesis is the claim.Is the test two-tailed, left-tailed, or right-tailed? Explain.Which test statistic will you use for your hypothesis test; z-test or t-test? Explain.What is the value of the test-statistic? Show your calculationWhat is the P-value? Explain how you determined it What is the critical value? Explain how you calculated itWhat is your decision? Reject the null or do not
reject the null? Explain why you made your decision including the
results for your p-value and the critical value.State the final conclusion in non-technical terms.
Please show your work for the construction of the test-statistic and explain your process for finding the p-value and critical value. You may use the Equation Editor to format your calculation steps on the Word document/ Attached is the word documents that will help with this assignment

Measures of Central Tendency
Simply reporting measures of central tendency or measures of variability will not tell the whole story. Using the following information, what else does a psychologist need to know or think about when interpreting this information?A school psychologist decided to separate some classes by gender to see if learning improved. She looked at student scores on the final exam and obtained the following information: Students in boy-girl classrooms obtained an average of 71.4 on their final exams with a standard deviation of 10.8 whereas students in single-gendered classrooms obtained an average of 75.9 on their final exams with a standard deviation of 8.2. She concludes that the single-gendered classrooms lead to better learning.1-2 paragraphs

GCCC Mod 15 Distribution of Sample Proportions of Alcohol Consumption Discussion
Learn by DoingHere are the directions, grading rubric, and definition of high-quality feedback for the Learn by Doing discussion board exercises. PromptThe National Health Survey uses household interviews to describe the health-related habits of U.S. adults. From these interviews they estimate population parameters associated with behaviors such as alcohol consumption, cigarette smoking, and hours of sleep for all U.S. adults.In the 2005-2007 report, they estimated that 30% of all current smokers started smoking before the age of 16. Imagine that we want to verify this estimate. So we randomly select a sample of 100 smokers and calculate the proportion who started smoking before the age of 16. How much error do we expect in the sample proportions if the 30% is correct for the population overall? Use the applet and a give an error based on 2 standard deviations.Here's the applet for the simulation:
