Solve the below problem:
Q: To determine whether a cleanup was necessary for a site that had been used for ammunition testing, 6 soil samples were taken from areas outside but close to the site, and 32 samples were taken from the site. This gave the sediment concentrations shown in Table for eight metals. Report on whether the site and the area outside the site are similar in terms of the mean concentration for each of the eight metals.
