Trap spacing measurements (in meters) for a sample of seven teams of red spiny lobster fisherman are reproduced in the accompanying table. Let u represent the average of the trap spacing measurements for the population of red spiny lobster
fisherman. The mean and the standard deviation of the sample measurements are x = 88.4 meters and s= 12.2 meters, respectively, Suppose you want to determine if the true value of u differs from 95 meters. Complete parts a through h below.

a. Specify the null and alternative hypotheses for this test.
OA. Ho: H= 95
H:u< 95
B. Hg: H= 95
H:H495
O. H : μ 95
Ha:H> 95
O D. Ho: H#95
HaiH = 95
b. Since x= 88.4 is less than 95, a fisherman wants to reject the null hypothesis. What are the problems with using such a decision rule?
O A.
To reject the null hypothesis, the problem must specify the critical value of t
OB. To reject the null hypothesis, the problem must specify the value of a and the probability that the test will lead to rejection and then consult the t or z table depending on the size of the sample.
O C. To reject the null hypothesis, the problem must specify the critical value of z.
O D. To reject the null hypothesis, the problem must specify the sample size.
