Problem

A rental agent claims that the mean monthly rent, mu, for apartments on the east side of town is less than $725. A random sample of 13 monthly rents for apartments on the east side has a mean of $724, with a standard deviation of $15. If we assume that the monthly rents for apartments on the east side are normally distributed, is there enough evidence to conclude, at the 0.1level of significance, that mu is less than $725?
