Title: A traffic study at one point on an interstate highway shows that vehicle speeds are normally ... Post by: Rene on Mar 3, 2018 A traffic study at one point on an interstate highway shows that vehicle speeds are normally distributed with a mean of 61.3 mph and a standard deviation of 3.3 mph. If a vehicle is randomly checked, find the probability that its speed is between 55.0 mph and 60.0 mph.
Q. 2 The mean of a normal probability distribution is 400 and the standard deviation is 10 . About 95 of the observations lie between what two values? Q. 3 Find the value of z(0.73) + z(0.27). Q. 4 Find the area between z(0.79) and z(0.43). Q. 5 The mean of a normal probability distribution is 500 and the standard deviation is 10 . About 68 of the observations lie between what two values? Q. 6 The value of z(0.10) z(0.90) is a. 2.56. b. -2.56. c. 1.28. d. -1.28. Q. 7 The value of z(0.70) z(0.30) is a. 1.04. b. -1.04. c. 0.52. d. -0.52.
