Design a study and go through the 4 steps discussed for hypothesis testing. In addition, show all of your work where applicable.

Describe your study

Step 1: State the hypotheses

Step 2: Set the criteria for a decision

Step 3: Collect data & compute sample statistics

Step 4: Make a decision

You can either make up your own sample data or use the following: population mean = 65, the standarddeviation of thepopulation = 15

Sample mean = 70, n=25

You would use the standard error of the sample and then the z score described during the lecture.
