Effect of an Outlier Test the effect of an outlier as follows: Use the sample data from Exercise 17 to find a 95% confidence interval estimate of the population mean, after changing the first value from 0.06 grams mile to 60 grams mile. This value is not realistic, but such an error can easily occur during a data entry process. Compare the two confidence intervals. Are the confidence interval limits sensitive to outliers? How should you handle outliers when they are found in sample data sets that will be used for the construction of confidence intervals?
