QUESTION 13 Metacritic is a website that aggregates reviews of music, games, and movies. For each product, a numerical score is obtained from each review and the website posts the average score as well as individual reviews. The website is somewhat similar to Rotten Tomatoes, but Metacritic uses a different method of scoring that converts each review into score in 100-point scale. In addition to using the reviewers quantitative ratings (stars, 10-point scale), Metacritic manually assesses the tone of the review before scoring. Historical data shows that these converted scores are normally distributed. One of the movies that the Metacritic rated was Zootopia, Based on the data from Metacritic on November 20, 2017, there are n-25 reviews, the sample average score is 72.63, and the sample standard deviation is 15.5 Use this information to answer next three questions. A 95% confidence interval for the true average score (M) of Zootopia is: [66.5540, 78.7060) [67.3352, 77.9284) [66.2316, 79.0284) [67.5305, 77.7295) QUESTION 14 A 99% confidence interval for the true average score (H) of Zootopia is [64.6444, 80.6156] [64.9084, 80.3552) (63.9593, 81.3007) [66.5540, 78.7060) QUESTION 15 Between the 95% and 99% intervals, which one is wider and why? The 99% interval since, in order to increase the confidence from the 95% to 99%, the margin of error should increase so that the intervals constructed using sampling will capture the true mean more often The 95% interval since, in order to decrease the confidence from the 99% to 95%, the margin of error should increase so that the intervals constructed using sampling will capture the true mean more often. The 99% interval because it is a more useful interval. The 95% interval because it is a less accurate interval. QUESTION 16 In hypothesis testing a Type Il error is committed when a true null hypothesis is rejected the critical value is greater than the value of the test statistic a true alternative hypothesis is not accepted sample data contradicts the null hypothesis
