Scientists need to be able to detect amounts of pollutants in the environment. Measurements were made on n 32 test specimens with a known mean concentration 2.35 ug/l of lead. It n was found that the > x; = 79.456 and > (x; – a)² = 1.0767. i=1 i=1 (a) If the population distribution of lead concentration is normal, state the minimum variance unbiased estimator of the mean. Then, compute the corresponding point estimate. Round your answer to 3 decimal places. (b) Find the estimated standard error of X. Round your answer to 3 decimal places. (c) Compute and interpret a 90% confidence interval for the true average lead concentration. (d) Did the interval you compute contain the true average? If it does not, is this a surprising result? Discuss. (e) Would you expect a wider or narrower interval if you were to compute a 95% confidence interval? Explain your answer without performing any computations.
