# Sony would like to test the hypothesis that the average age of a PlayStation user is different fromthe average age of an Xbox user. A random sample of 36 PlayStation users had an average age of

34.2 years while a random sample of 30 Xbox users had an average age of 32.7 years. Assume thatthe population standard deviation for the age of PlayStation and Xbox users is 3.9 and 4.0 years,respectively. Sony would like to set ΅=0.10. The conclusion for this hypothesis test would be thatbecause the absolute value of the test statistic isA)more than the absolute value of the critical value, we can conclude that the average age ofPlayStation users is different from the average age of Xbox users.B)more than the absolute value of the critical value, we can conclude that the average age ofPlayStation users is equal to the average age of Xbox users.C)less than the absolute value of the critical value, we cannot conclude that the average age ofPlayStation users is different from the average age of Xbox users.D)less than the absolute value of the critical value, we cannot conclude that the average age ofPlayStation users is equal to the average age of Xbox users.Uploaded by: RBSD44
