A sample of 100 yields x macr 24 the population standard


Consider the following hypothesis test.

H_0: μ ≥ 25

H_1: µ < 25

A sample of 100 yields x ¯ = 24. The population standard deviation is 12. If a = .05, find the acceptance/rejection region H_0 and determine if you accept or reject the hypothesis H_0 (Draw graph!).

What is the p-value?

Please show step-by-step work, including formulas used. I am trying understand how to solve the problem. Please recognize that you are the expert, however I myself have not taken a math course in almost 10 years
