1. A claim is made that the average salary for all jobs in Minnesota is less than $65,000. You are going to test the claim using a=0.05 and assume that your data is normally distributed and the population standard deviation is not known.
2. Write the null and alternative hypotheses symbolically and identify which hypothesis is the claim. Then identify if the test is left-tailed, right-tailed, or two-tailed and explain why.
