A car manufacturer struggles with quality problems. Maximum speeds of 500 cars manufactured in the factory (rounded to the nearest 0.5 mph) are approximately normally distributed with mean 171.5 mph and standard deviation 7.8 mph. Apply Normal approximation on discrete observations to calculate the following values. Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. (a) The number of cars that are expected to have a maximum speed less than 153.0 mph is. (Round to the nearest integer.) (b) The number of cars that are expected to have a maximum speed between 168.5 and 180.0 mph (both inclusive) is. (Round to the nearest integer.) (c) The number of cars that are expected to have a maximum speed equal to 172.0 mph is (Round to the nearest integer.)
