Vehicle speed on a particular bridge in China can be modeled as normally distributed.
(a) If 5% of all vehicles travel less than 39.13 m/h and 10% travel more than 73.23 m/h, what are the mean and standard deviation of vehicle speed?
(b) What is the probability that a randomly selected vehicle's speed is between 50 and 65 m/h?
(c) What is the probability that a randomly selected vehicle's speed exceeds the speed limit of 70 m/h?

The wind speed in Laramie, Wyoming is normally distributed. The average wind speed for the state of Wyoming is approximately 20 mph. A curious student wanted to find out if the wind speed in Laramie was different than the state average. They took a sample of 25 random days in Laramie, measured the wind speed, and found an average of 18 mph with a standard deviation of 7.8 miles per hour. Test the claim that the average wind speed in...
