Question:
Exercise 6-40 presented data on the concentration of suspended solids in lake water.
(a) Test the hypothesis H0: μ = 55 versus H1: μ ≠ 55; use α = 0.05. Find the P-value.
(b) Check the normality assumption.
(c) Compute the power of the test if the true mean concentration is as low as 50.
(d) What sample size would be required to detect a true mean concentration as low as 50 if you wanted the power of the test to be at least 0.9?
