Ch 8 FRQ ( The distribution of average speeds of the top 53 drivers in NASCAR is roughly symmetric, unimodal, and bell-shaped, with a mean of 184.8 mph and a standard deviation of 7.2 mph. In the space above, draw a Normal Curve, from z=-3 to z=+3. Draw vertical lines at the mean and each whole number standard deviation above and below the mean. Write two rows of numbers under the base line; one row with the number of standard deviations above and below the mean (z-scores), and a row under that with the actual values for this problem. ] What percent of drivers would you expect to have speeds below 199.2 mph ? Show all work. s] What is the area under the curve to the left of a speed of 170.4mph Show all work. What is the probability that a driver selected at random will have a speed below 172.0 mph ?
