11.3.15-T Question Help A researcher wanted to determine if carpeted rooms contain more bacteria than uncarpeted rooms. Full data set The table shows the results for the number of bacteria per cubic foot for both types of rooms. Carpeted Uncarpeted 11 10.8 11.8 5 9.5 12.8 11.6 8.7 16 6.7 12.8 4.7 13.4 9.3 6.9 10.8 Determine whether carpeted rooms have more bacteria than uncarpeted rooms at the a = 0.01 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. O A. HO: H1 = H2 Hy: H1 H 2 OD. HO: H1 = H2 H1 : H1 > H2B) Determine the P-value for this hypothesis test. P=? C) State the appropriate conclusion. Choose the correct answer below. - Upper H 0H0. There isis significant evidence at the alpha equals 0.0ld=0.01 level of significance to conclude that carpeted rooms have more bacteria than uncarpeted rooms. -Do not reject Upper H 0H0. There is not significant evidence at the alpha equals 0.0la=0.01 level of significance to conclude that carpeted rooms have more bacteria than uncarpeted rooms. - Reject Upper H 0H0. There is not significant evidence at the alpha equals 0.01u=0.01 level of significance to conclude that carpeted rooms have more bacteria than uncarpeted rooms. - Reject Upper H 0H0. There is significant evidence at the alpha equals 0.0lu=0.01 level of significance to conclude that carpeted rooms have more bacteria than uncarpeted rooms
