5. Keep-On-Trucking (KOT) is a national trucking company. The number of physical damage claims to KOT freight trucks in a given year is normally distributed with a mean of 260 and a standard deviation of 40. Based on these parameters, perform the following calculations. (note: use the "Areas Under a Normal Curve table provided as part of the notes for Chapter 5) Fisrt step: draw a picture a. What is the probability in a given year that fewer than 280 physical damage claims will occur? (1.5 points) b. What is the probability in a given year that between 240 and 290 physical damage claims will occur? (1.5 points) C. Above what number of physical damage claims do the highest 20 percent of all physical damage claims in a given year fall? (1 point)
