Question: The examples in this section used the axial loads of a sample of cans 0.0109 in. thick and a second sample of cans 0.0111 in.

The examples in this section used the axial loads of a sample of cans 0.0109 in. thick and a second sample of cans 0.0111 in. thick. (The original data are listed in Data Set 15 of Appendix B.) We noted that the second sample includes an outlier of 504 lb. How are the box plots, the hypothesis test, and the confidence interval affected if we decide that the outlier is actually an error that should be deleted?
