Calculate a 95% confidence interval for the population mean, based on sample 1.5, 1.54, 1.55, 1.51, 0.09, 0.08, 1.60, 0.17, 0.99, 0.98, 1.12, 1.13, 1.00, 1.56, and 1.53. Change last number from 1.53 to 50 and recalculate confidence interval. Using the results, explain the effect of outlier or extreme value on confidence interval.
