Assuming that the population is normally distributed, construct a 90 % confidence interval for the population mean, based on the following sample size of n equals 5. 1, 2, 3, 4, and 29 In the given data, replace the value 29 with 5 and recalculate the confidence interval. Using these results, describe the effect of an outlier (that is, an extreme value) on the confidence interval, in general.
