Question

Assuming that the population is normally distributed, construct a 95% confidence interval for the population mean, based on the following sample size of n=8.

Assuming that the population is normally distributed, construct a

confidence interval for the population mean, based on the following sample size of


1, 2, 3, , and   

In the given data, replace the value

with 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   confidence interval for the population mean, using the formula or technology.

Round answer to two decimal places
