Think of an application where you can use hypothesis testing to test a premises. Use .05 for your alpha and give the scenario. Set up the problem, solve it and state your conclusions. See the example below. Then respond to at least 2 classmates.
First post: First summarize the 3 videos and make a note of what you learned. Then create your own hypothesis test. For instance, XYZ car company boast that it’s new car Eco Auto gets at least 59 miles to the gallon. Given a sample mean of 57 and a standard deviation of 3.5 where 35 people were tested, find the z value and p score. Hint: Use the P value calculator in the announcements to find the p score. Note: On this one you do not need to attach an excel spreadsheet.
You can put this in excel or your calculator
or enter this in excel
and hit enter
Then take that value which we will call A
and type this in excel
and hit enter
Using the z to p value calculator with a=.05, 1 tailed test and z=3.38, you get
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.
