Suppose the Annual rainfall (in inches) in 5 different locations in Hawaii are: 28, 18, 18, 16, 14. A statistician wants to use this data to test the claim that the average rainfall in Hawaii is more than 16 inches. Assume significance level α=0.05 .   

a. What is the alternative hypothesis H1? What tailed test is this?

b. Determine the value of the Test Statistic.

c. What is the P-value?

d. Should the statistician Reject or Fail to Reject the Null Hypothesis?

e. What is the conclusion in plain English? (use the summary table provided in class)

f. Calculate the 90% Confidence Interval for the average rainfall in Hawaii

g. Are the confidence limits (in part (f)) consistent with the conclusion in part (e)? Why or why not?

Suppose that the average trip time from Oak Park to UIC on the Blue line is 22 minutes and that the standard deviation of the population is 16 minutes (sigma=16). We are interested to know whether the average trip time on Thursdays is longer. We study a sample of 49 trips on Thursdays and the average is 23.75 minutes. Execute a hypothesis test at alpha=5% that the average trip time on Thursdays is longer (that is, that it requires a...

steel factory produces iron rods that are supposed to be 36 inches long. The machine that makes these rods does not produce each rod exactly 36 inches long. The lengths of these rods vary slightly. It is known that when the machine is working properly, the mean length of the rods is 36 inches. According to design, the standard deviation of the lengths of all rods produced on this machine is always equal to .05 inches. The quality control department...
