Among varions ethnic groups, the standard deviation of heights is known to beapproximately three inches. A Forty-cight male Swedes are surveyed. The sample meanis 71 inches. A 95% confidence interval for the population mcan height of male Swedesis:O (71.167,72.833 )O ( 70.238,71.762)O (70.167,71.833 )O (70.151,71.849)

Critical value: Using Excel formula “=NORM.S.INV(1-(0.05/2))”, the critical value for 95% confidence…

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 51 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. (a)What is the level of significance? =__ State the null and alternate hypotheses. A-H0: ? = 19 in; H1: ? ≠ 19 in B-H0: ? < 19 in; H1: ? = 19 in C-H0: ? = 19 in; H1: ? < 19 in D-H0: ? = 19 in; H1: ? > 19 in E-H0: ? > 19 in; H1: ? = 19 in (b)What sampling distribution will you use? Explain the rationale for your choice of sampling distribution. A-The Student's t, since the sample size is large and ? is known. B-The standard normal, since the sample size is large and ? is known.
