Construct a 99% prediction interval for the top speed of a hybrid or electric car in Exercise 17 that has a combined city and highway fuel economy of 90 miles per gallon equivalent

Construct the indicated prediction interval and interpret the results.

Data from Exercise 17:

The table shows the combined city and highway fuel efficiency (in miles
per gallon gasoline equivalent) and top speeds (in miles per hour) for nine hybrid and electric cars. The regression equation is ŷ = -0.465x + 139.433.
