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.
1,2,3,4,5,6,7 and 25
Change the number 25 to 8 and recalculate the confidence interval. Using these results, describe the effect of an outlier ( that is, an extreme value) on the confidence interval.
Find a 95% confidence interval for the population mean.
Round the decimal two places as needed.
