Question:
A sample of 64 observations is selected from a normal population. The sample mean is 215, and the sample standard deviation is 15. Conduct the following test of hypothesis using the .05 significance level. Use the template we followed in class and for weekly assignments showing all the problem information and all 5 steps of the hypothesis testing process. Note here we do not have a verbal hypothesis, you have to extract some information from the Hypothesis symbols below. Show a number line along with your final decision.
H 0: u => 220
H 1: u < 220
