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.

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. A. Ho: H1= H2 H1: H1> H2 B. Ho: H1 <H2 H1: H1 > H2 c. Hoi H1= H2 H1: H1<H2 D. Ho: H1=H2 H1: H1##2 Determine the P-value for this hypothesis test. P-value = (Round to three decimal places as needed.) State the appropriate conclusion. Choose the correct answer below. OA. Do not reject Ho. There is not significant evidence at the a = 0.05 level of significance to conclude that carpeted rooms have more bacteria than uncarpeted rooms. OB. Reject Ho. There is significant evidence at the a = 0.05 level of significance to conclude that carpeted rooms have more bacteria than uncarpeted rooms. Oc. Do not reject Ho. There is significant evidence at the a = 0.05 level of significance to conclude that carpeted rooms have more bacteria than uncarpeted rooms. OD. Reject Ho. There is not significant evidence at the a = 0.05 level of significance to conclude that carpeted rooms have more bacteria than uncarpeted rooms.
