The table shows the total square footage (in billions) of retailing space at shopping centers and their sales (in billions of dollars) for 10 years. Construct a 90% prediction interval for sales when the total square footage is 5.8 billion. The equation of the regression line is y=501.564x-1614.581.

Interpret the prediction interval. A There is a 90% chance that the predicted sales given 5.4 billion square feet of shopping area is within the prediction interval OB. You can be 80% confident that the sales will be within the prediction interval when the total square footage is 5.4 billion square feet OC. A randomly selected year with 5.4 billion square feet of shopping area has a 90% probability of being within the prediction interval
