Assuming that the population is normally distributed, construct a 99% confidence interval for the population mean, based on e ollowing sample sizeof 1, 2, 3, 4, 5, 6, 7, and 25 In the given data, replace the value 25 with 8 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. Find a 99% confidence interval for the population mean, using the formula or technology....
Assuming that the population is normally distributed, construct a 99% confidence interval for the population mean for each of the samples below. Explain why these two samples produce different confidence intervals even though they have the same mean and range.
