Supposeyou administer a certain aptitude test to a random sample of 9 students in yourhigh school, and the average score is 105. Assume a standard deviation of σ =15 for the test. We want to test that the average aptitude test is more than100 at the α = 0.05 level. List out the five steps in hypothesis testing andbe sure to write sentences.

For example step (1) might be
(1) Compute the standard deviation for use in computing the z for using the Central Limit Theorem.
So far
known
n = 9
Xmean = 105
σx = 15
Hypothesis
H0: μx <= 100
H1: μx > 100
Signaficance level is
α =0.05
Test, because this Is a one tail test
Z=X-u/σ/sqrt n,
Z=(105 - 100) (15/sqrt(9)
Z = 1
I'm guessing at this P value needs to be found?
