A random sample of 16 peopleunder 25 years of age who live in a university neighborhood were surveyed. The surveyshowed that they spent a sample mean amount of $3,220 with sample standard deviation$750. Test the claim that the mean for this neighborhood is different from the nationalaverage. Use a 5% significance level. Assume our data is normally distributed.a) State the null and alternate hypotheses.b) Would you perform a one-tailed or two-tailed test?
