# Question: Refer to the National Highway Traffic Safety Administration NHTSA crash

Refer to the National Highway Traffic Safety Administration (NHTSA) crash tests of new car models, presented in Exercise. A summary of the driver-side star ratings for the 98 cars in the CRASH file is reproduced in the accompanying MINITAB printout. Assume that 1 of the 98 cars is selected at random, and let x equal the number of stars in the car’s driver-side star rating.

a. Use the information in the printout to find the probability distribution for x.

b. Find P(x = 5).

c. Find P(x ≤ 2).

a. Use the information in the printout to find the probability distribution for x.
