Many people like to play app based games on their mobile devices. Suppose we would like to estimate the average amount of time (in hours) per week students have played an app-based game on their mobile device at CSU Stan. In order to do this, we take a random sample of 20 students and ask them how many hours they have played an app- based game in the last week. The following data were collected: 11 4 5.5 5.5 6 7 7.5 6.2 10 2 10 2.5 7.5 6 7 9 Which of the following is the correct 99% confidence interval for the estimate of the average number of hours (per week) that all CSU Stan students have played an app- based game? [5.28, 7.59] [4.86, 8.01] [5.48,7.39] [5.86, 7.01]

Many people like to play app based games on their mobile devices. Suppose we would like to estimate the average amount of time (in hours) per week students have played
an app-based game on their mobile device at CSU Stan. In order to do this, we take a random sample of 20 students and ask them how many hours they have played an app-
based game in the last week. The following data were collected:
11

Which of the following is the correct 99% confidence interval for the estimate of the average number of hours (per week) that all CSU Stan students have played an app-
based game?
[5.28, 7.59]
[4.86, 8.01]
[5.48,7.39]
[5.86, 7.01]
