A person records the speeds of various cars as they drive past their house. After 100 readings,the speeds of the cars are normally distributed with a mean of 23.84 mph and a standarddeviation of 3.56 mph.a. If a car's speed has a z-score of -2, what speed was that car going?b. Calculate the z-score for a car that is driving at 28 mph.c. One car is observed as driving at 30 mph, and another at 15 mph. Which of the two ismore unusual?
