exam ff 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 normal probability plot and Full data set 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 of significance?

Select the correct choice below and fill in the answer box within your choice (Round to three decimal places as needed.) OA /2= O B. la= Do carpeted rooms have more bacteria than uncarpeted rooms at the a = 0 05 level of significance? O A. Yes, because the test statistic is not in the critical region. O B. No, because the test statistic is not in the critical region. O C. Yes, because the test statistic is in the critical region O D. No, because the test statistic is in the critical region.
