For Exercises 15–24, use the data and the regression equations that you calculated in the Section 13.1 exercises.

Question 13.100

  1. Construct a 99% prediction interval for the total sales for a randomly chosen video game that has been on the top list for 20 weeks.
  2. Suppose we were asked to provide a prediction interval for the total sales for a randomly chosen video game that has been on the top list for 104 weeks. Explain what the danger would be in constructing such a prediction interval.
