Reference no: EM13117201

Compute a 90% confidence interval or the population mean, based on the sample 67, 76, 52, 70, 69, 59, 75, 72, 53, and 257. Change the last number from 257 to 61 and recalculate the confidence interval. Using the results, describe the effect of an outlier or extreme value on the confidence interval.
