MAT 2100 Final Exam STUDY GUIDE Skip to Main Content Question 31 of 40 (1 point) | Question Attempt: 1 of 1 Time Remaining: 43:08 Takaila ✓ 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 80. In a random sample of 33 players, the mean rating is 86.3. Assume the population standard deviation of the ratings is known to be 22.8. Is there enough evidence to support the claim that the mean player rating is higher than 80? Perform a hypothesis test, using the 0.10 level of significance. Español (a) State the null hypothesis Ho, and the alternative hypothesis H₁. μ X Ho: ☐ H₁: □<ロ □□ □≠□ 0

So, there is enough evidence to support the claim that the mean player rating is higher than 80. O Since the p-value is less than (or equal to) the level of significance, the null hypothesis is not rejected. So, there is not enough evidence to support the claim that the mean player rating is higher than 80. O Since the p-value is greater than the level of significance, the null hypothesis is rejected. So, there is enough evidence to support the claim that the mean player rating is higher than 80. O Since the p-value is greater than the level of significance, the null hypothesis is not rejected.
