Help with step 3 only

Mary read many studies that said that Professors tend to be happier than those in other professions. She was interested to see if that was true forCommunity College Professors. We know that people, on average, report feeling a "5" on a happiness scale, with a standard deviation of 1.2. Professor Caroline Gee said she would rate herself as a "9" on the happiness scale. Do the 6 steps to inferential statistics to see if Professor Gee is happier than average people.

1) Is Professor Gee happier than average people?

2) Ho: Professor Gee is NOT happier than average people

Ha: Professor Gee is happier than the average people

3) Need help with 3 - I prefer to draw rather than writing it out. I need help finding my rejection regions with a z table, which values am I looking up?

4) 9-5/1.2 = S/1.2 = 4.83

5) I will do on my own

6) I will do on my own
