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 a 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.
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 from your instructor.
First post: Given a sample mean (xbar) of 57 and a population standard deviation sigma (σ) 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 (µ) 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 µ< 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: µ=59
Ha: µ<59
You can put this in excel or your calculator
Z=(xbar-µ)/(σ/ sqrt n) where xbar=57, µ=59, population standard deviation sigma σ = 3.5 and n=35
=-3.38
Using the z to p value calculator

with α=.05, 1 tailed test and z=-3.38, you get
p=.000362
Since p < .05, you reject the null.
You will want to respond to 2 classmates. Keep the conversation going by mentioning the video and tell what you learned. Also mention how the hypothesis test helped you.
To earn full credit for this discussion, you must respond to at least two (2) of your peers and post your initial post by Thursday.
