According to the Entertainment Software Association, the average age of "gamers" (those that routinely play video games) is 34 years old. A random sample of 33 gamers people had an average age of 36.7 years old. Assume that the population standard deviation for the age of gamers is 4.6 years. Use a 90% confidence interval to test the validity of this report and choose the statement that is correct. O A. The report by the Entertainment Software Association is not validated because this confidence interval does not include 34 years. O B. The report by the Entertainment Software Association is not validated because this confidence interval does include 34 years. OC. The report by the Entertainment Software Association is validated because this confidence interval does include 34 vears. O D. The report by the Entertainment Software Association is validated because this confidence interval does not include 34 years.

The principal at a large high school claims that students spend at least 10 hours per week doing homework, on average. To investigate this claim, an AP Statistics class selected a random sample of 250 students from their school and asked them how long they spent doing homework during the last week. The sample mean was 10.2 hours and the sample standard deviation was 4.2 hours. Construct and interpret a 95% confidence interval for the mean time that students at this school spent doing homework in the last week. Based on your interval, what can you conclude about the principal's claim? What is your t* value? Remember to use the conservative DF value.
