Q: One possible side effect of air pollution is genetic damage. A study designed to examine this problem exposed one group of mice to air near a steel mill and another group to air in a rural area and compared the number of mutations in each group. Here are the data for a mutation at the Hm-2 gene locus:
Mutation

Rural air
|

b). Summarize the data numerically and graphically.
c). Is there evidence to conclude that the location is related to the occurrence of mutations? Perform the significance test and summarize the results.
