Starting Salary Problem In 2013, the mean starting salary for college graduates who major in Social Work was $45,000. An analyst for a job searching company claims that the mean starting salary has since decreased. In a random sample of 38 job posting for social workers, the mean starting salary was $43,200 with a standard deviation of $9,340. Test the claim using a significance level of 0.10. Determine the p-value. Round your answer to 4 decimal places.
