Pyramid Lake is on the Paiute Indian Reservation in Nevada. The lake is famous for cutthroat trout. SuPpose a friend tells you a random sample of 46 fish caught, the mean length was x = 18.6 inches, with estimated standard deviations = 3.5 inches. Do these data indicate that the average length of a trout caught in Pyramid Lake is less thanu= 19 inches? Use a = 0.05. the average length trout caught in Pyramid Lake is u- 19 inches. However, a survey reported that o A USE SALT (a) What is the level of significance? State the null and alternate hypotheses.

Explain the rationale for your choice of sampling distribution. The Student's t, since the sample size is large and e is unknown. The standard normal, since the sample size is large and e is unknown. The standard normal, since the sample size is large and e is known. The Student's t, since the sample size is large and e is known. What is the value of the sample test statistic?

Question
Help me answer the questions in the pictures with the following information:
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, 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 ? = 19 inches? Use ? = 0.05.
