Pixar hopes to produce the Cars 4 movie in 2025, and would like to know what proportion of Cars 3 viewers saw Cars 2. If this percentage is greater than 75%, they'll design some ads primarily for viewers already familiar with the Cars sequence. Suppose the marketing division takes a random sample of Cars 3 viewers and finds 84% who had seen Cars 2, leading to p-value = 0.012. (a) If more than 75% of Cars 3 viewers saw Cars 2, one segment of the marketing division will focus on designing ads for Cars 4 for viewers familiar with the Cars sequence. Based on the p-value of 0.012, what should they do, for ? = 0.05? (Design/ Don't design) ads for Cars 4 for viewers familiar with the Cars sequence. There is (sufficient/ insufficient) evidence to conclude the proportion of Cars 3 viewers saw Cars 2 is greater than 75%. (b) Suppose the percentage of Cars 3 viewers who saw Cars 2 is really equal to 75%, and the marketing strategist makes the wrong conclusion. Which type of error did they make? A. Type I error B. Type II error C. Both Type I and Type II error
