Problem 9

A study examined the relationship between tire width (in units of millimeters) and braking distance (in units of meters) for a set of sports cars. For a tire width of 245245 millimeters, the statistical software output produces a 9595 percent prediction interval for braking distance as 39.739.7 to 49.349.3 meters. What is the 95%95\% prediction interval estimate for braking distance for a car with 245245-millimeter-wide tires, and what does this interval mean?
