A rental agent claims that the mean monthly rent, µ, for apartments on the east side of town is less than $675. A random sample of 22 monthly rents for apartments on the east side has a mean of $665, with a standard deviation of $25. If we assume that the monthly rents for apartments on the east side are normally distributed, is there enough evidence to conclude, at the 0.10 level of significance, that u is less than $675? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) (a) State the null hypothesis H and the alternative hypothesis H,. Ho :0 H :0 (b) Determine the type of test statistic to use. D=0 OSO (Choose one) (c) Find the value of the test statistic. (Round to three or more decimal places.) O
