A student is doing a regression analysis on a data set with an X variable with mean of 5020 parts per million, a minimum of 4300 parts per million and a maximum of 5800 parts per million. They calculate the following prediction intervals for x=5200ppm, x=4500ppm, and x=4100ppm, but mixed up which interval corresponds to which x. • A: (158.39, 164.79)
• B: (164.79, 170.39)
• C: (175.59, 180.59)
With no other information, match prediction interval A, B, and C to the corresponding value of x. How do you know which interval is associated with which X? 6.
One of the intervals in the previous question is invalid: which value of x does it correspond to and why is it invalid?
