After a lot of 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 84. In a random sample of 68 players, the mean rating is 87.5. Assume the population standard deviation of the ratings is known to be 14.3. Is there enough evidence to support the claim that the mean player rating is higher than 84? Perform a hypothesis test, using the 0.05 level of significance. (a) State the null hypothesis H and the alternative hypothesis H,. ロ<ロロSロロ>ロ H: 0 ロ2ロロ=ロロォロ (b) Perform a Z-test and find the p-value. Here is some information to help you with your Z-test. の
