Suppose a friend tells you that the average length of trout caught in Pyramid Lake is u = 19 inches. However, a survey reported that of a random sample of 46 fish caught, the mean length was x = 18.6 inches, with estimated standard deviation s = 3.5 inches. Do these data indicate that the average length of a trout caught in Pyramid Lake is less than At = 19 inches? Use a = 0.05. LO USE SALT (a) What is the level of significance? State the null and alternate hypotheses. O Holl = 19 in; Hi: M # 19 in O Ho: M = 19 in; Hi M 19 in O Ho:Ml > 19 in; Hy: LL = 19 in O Holl 0.010 0.0010
