After a hard work, a studio releases a new video game. The studio believes that the game will be liked by players; in particular, the studio claims that the mean player rating, µ, will be higher than 75. In a random sample of 37 players, the mean rating is 82.7. Assume the population standard deviation of the ratings is known to be 28.6 . Is there enough evidence to support the claim that the mean player rating is higher than 75? Perform a hypothesis test, using the 0.10 level of significance. (a) State the null hypothesis H and the alternative hypothesis H,. Ho: H= 75 O<O OSO O>O H: u > 80 O=0 ロロ (b) Perform a Z-test and find the p-value. Here is some information to help you with your Z-test. • The value of the test statistic is given by
