After a lot of work, a studio launches a new video game. The studio believes that gamers will like the game and in particular, states that the average rating,μ, that the players will grant you will be greater than85. The mean score of a random sample of54players is92.1.Suppose the population standard deviation of the scores is known to be21.1. Is there enough evidence to support the claim that the average player rating is higher than85? Perform a hypothesis test using the significance level of0.10.
