Problem (One tailed test)

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?

Question

--H0 (null hypothesis):
-H1 (alternative hypothesis):
-Type of test statistic: (Z, t, F, chi squared)
-The value of the test statistic (round to at least 3 decimal places):
-The p-value (round to at least 3 decimal places): ___
-Using the 0.1 level of significance, can we conclude that the mean monthly rent for apartments on the east side is less than \$725? (yes, no)
