A researcher for a consumer advocacy group belleves that, due to the construction of newer apartment complexes in neighboring towns, the mean monthly rent on the east side, He is now lower. A random sample of 10 monthly rents for apartments on the east side has a mean of S660, with a standard deviation of S25. Assume that current monthly rents for apartments on the east side are approximately normally distributed. Based on the sample, is there enough evidence to conclude, at the 0,10 level of significance, that the population mean monthly rent is now less than what is stated on the website? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formufas.) (a) state the null hypothesis H, and the alternative hypothesis is 1 0 P H=0 H: ce d. DESD (0) Determine the type of test statistic to use (Choose one) Find the value of the test statistic. {Round to three or more decimal places . (d) Find the p-value. (Round to three or more decimal places LE 01 (e) Can we conclude that the mean monthly rent for apartments on the east side is less than what is stated on the website? Yes No
