Using Chi-square table finding the P-value and interpret the result
One possible side effect of air pollution is genetic damage. A study designed to examine this problem exposed one group of mice air near a steel mill and another group to air in a rural area. The study compared the number of Hm-2 gene mutations in each group. The data table is below.

a) Estimate the p-value from Table F.
b) At the 5 percent level, is there evidence to conclude that location and mutation are related?
