Test whether the median amount of bacteria in carpeted rooms was greater than the median amount of bacteria in uncarpeted rooms at the a0.05 level of
significance. Is there sufficient evidence to support the claim?
OA. No, there is not suficient evidence. The test-statistic is in the critical region
OB. Yes, there is suficient evidence. The test-statistic is in the critical region
O C. No, there is not sufficient evidence. The test-statistic is not in the critical region
O D. Yes, there is suficient evidence. The test-statistic is not in the critical region
