A researcher wanted to determine if carpeted or uncarpeted rooms contain more bacteria. The table shows the number of bacteria per cubic foot for random samples of both types of rooms. Carpeted 9.6 9.5 8.8 8.9 9.2 9.9 9.1 8.9 O A. Yes, there is sufficient evidence. The test-statistic is in the critical region OB. Yes, there is sufficient evidence. The test-statistic is not in the critical region OC. No, there is not sufficient evidence. The test-statistic is not in the critical region O D. No, there is not sufficient evidence. The test-statistic is in the critical region Full data set Uncarpeted 12.2 10.8 13.3 10 10.1 12.6 9 12.3 Test whether the median amount of bacteria in carpeted rooms was greater than the median amount of bacteria in uncarpeted rooms at the a= 0.05 level of significance. Is there sufficient evidence to support the claim?
