Exercise 6-40 presented data on the concentration of suspended solids in lake water.

(a) Test the hypothesis \(H_0 : \mu = 55\) versus \(H_1: \mu \neq 55\); use \(\alpha = 0.05\). 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?
