Use the fоllоwing infоrmаtion to аnswer questions 11 through 15. A mobile аpp developer is trying to determine which of two methods of advertisement keeps its customers watching ads longer. In particular, the app developer wants to see if method A provides longer ad watching times than method B, at the 10% significance level. The app developer randomly selected 20 customers to receive method A of ad delivery, and another 20 customers were randomly selected to receive method B of ad delivery. It was found that customers under method A watched their ads for an average of 48.7 seconds with a standard deviation of 16.3 seconds. Customers from method B watched their ads for an average of 42.1 seconds with a standard deviation of 12.4 seconds. You may assume the values for both populations are approximately normal. We will use the pooled variance to test the hypotheses that the ad watching times are equal versus the ad watching times for group A are larger:
