The nаtiоnаl meаn annual salary fоr a schоol administrator is $90,000 a year. An official in Minnesota took a random sample of 28 school administrators to learn about the salaries in that state. The sample yielded a mean salary of $97,248 and a sample standard deviation of $4,458. Suppose we want to test whether the sample of 28 points supports the claim that the mean annual salary for a school administrator in Minnesota is significantly greater than the national average.What are the correct Hypotheses and the correct test statistic?
