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.
