A researcher wanted to determine if carpeted or uncarpeted rooms contain more bacteria. The table shows the results for the number of bacteria per cubic foot for both types of rooms. A normalprobability plot and boxplot indicate that the data are approximately normally distributed with no outliers. Do carpeted rooms have more bacteria than uncarpeted rooms at the a = 0.05 level ofsignificance?Full data setCarpetedUncarpeted5.99.214.913.53.89.26.86.17.18.46.69.412.6 6.510.1 10.5Click the icon to view the Student t-distribution table.What are the pull and alternative hynotheses?

Select the correct choice below and fil in the answer box within your choloe.(Round to three decimal places as needed.)Do carpeted rooms have more bacteria than uncarpeted rooms at the a0.01 level of significance?OA. Yes, because the test statistic is not in the oritical region.OB. No, because the test statistic is in the critical region.OC. No, because the test statistic is not in the critical region.OD. Yes, because the tost statistic is in the critical region.
