Note: You are expected to write down the likelihood function and loglikelihood function and maximize the loglikelihood function with respect to µ . (b) Construct a 95% confidence interval for µ . (c) How large a sample is required if we want to be 95% confident that our estimate of µ is off by less than 0.05 ppm. Problem #3: 9.12 (Here 2.45 is the sample standard deviation): (10.15, 12.45). Problem #4: 9.25 (Prediction interval): (6.05, 16.55). Practice problem: Not required for anyone. 9.4 and 9.8...
