A rental agent claims that the mean monthly rent,u, 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$714, with a standard deviation of 21 . If we assume that the monthly rents for apartments on the east side are normally distributed, is there enough evidence to conclude, at the0.1 level of significance, thatu is less than $725?

Perform a one-tailed test. Then fill in the table below.

Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)
