Table 5.13 (page 237 in the textbook) shows the observed pollution indexes of air samples in two areas of a city. Using a Statistical software, test the hypothesis that the mean pollution indexes are the same for the two areas using? = 0.05. Check the normality of data sets using a graphical method (hint: side-by-side boxplot). Be sure to include the edited computer output and to interpret the results.
