The national mean annual salary for a school administrator is $90,000 a year. A school official took a sample of 25 school administrators in the state of Ohio to learn about salaries in the state to see if they differed from the national average. (if you can do this in excel and past in the formulas you will get the top rating).
a. Formulate hypotheses that can be used to determine whether the population mean annual administrator salary in Ohio differs from the national mean of $90,000.
b. What is the p-value for your hypothesis test in part (a)? Sample data for 25 Ohio administrators at the bottom of question.
c. At a= .05, can your null hypothesis be rejected? What is your conclusion?
d. Repeat the preceding hypothesis test using the critical value approach.
