1. Assuming that the population is normally distributed, construct a 95% confidence interval for the population mean, based on the following sample size of n=6.

1, 2, 3 4,5, and 19

In the given data, replace the value 19 with 6 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 95% confidence interval for the population mean, using the formula or technology.

_____ ____
