First, summarize the 3 videos from the links above and then think of an application where you can use hypothesis testing to test a premise. Give a scenario similar to what is in the first post below. Use .05 for your alpha.

Then for your 2 responses select 2 students who have posted the first post and set up their problem, solve it and state your conclusions. See the example below. Show your work by inserting the values in the formula and drawing a conclusion.

Review of instructions requirements ...

You MUST provide the correct answer for your problem -- an answer key, so that classmates will know whether or not their answers to you are correct. Let the classmate provide the details of HOW they worked the problem.

For your responses, pick 2 classmates. On each, post a copy of their problem, and then show your work explaining HOW you worked the problem IN DETAIL with your answer. Of course, there will be more than one comment on each person's work. Be helpful in your answers to your classmates.

Example:

Don't use the numbers in this example post in your post. Please make sure all posts are unique and use different numbers.

It is important to go back and read follow-up responses.

First post: Given a sample mean (xbar) of 57 and a population standard deviation sigma () of 3.5 from a previous study where n= 35 values, find the z value and p value. The data indicates that the population mean () for the new car Eco Auto is 59 miles per gallon but we think it may be lower based on our data. Test the claim that < 59. Hint: Use the P value calculator in the announcements to find the p value. Note: On this one you do not need to attach an excel spreadsheet.

Student Response:

Ho: =59

Ha: <59

What would be my answer if I chose

HO: 22

HA: 25
