Determine whether carpeted rooms have more bacteria than uncarpeted rooms at the a = 0,05 level of significance. Normal probability plots indicate that the data
are approximately normal and boxplots indicate that there are no outliers.
State the null and alternative hypotheses. Let population 1 be carpeted rooms and population 2 be uncarpeted rooms.
