Question: Assuming that the population is normally distributed, construct a 90% confidence interval for the population mean, based on the following sample size of n=5 1,2,3,4,21

Assuming that the population is normally distributed, construct a 90% confidence interval for the population mean, based on the following sample size of n=5

1,2,3,4,21

in the given data, replace the value 21 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.

Find a 90% confidence interval for the population mean, using the formula or technology.
