.Pyramid Lake is on the Paiute Indian Reservation in Nevada. The lake is famous for cutthroat trout. Suppose a friend tells you that the average length of trout caught in Pyramid Lake
is ? = 19 inches. However, the Creel Survey reported that of a random sample of 49 fish caught, the mean length was ?̅= 18.5 inches, with estimated standard deviation ? = 3.2 inches. ? = 0.05.

d, Compute the sample test statistic.
e. Using the P-value method, estimate the P-value for the test.
f. Do we reject or fail to reject ?0? Interpret the results
