Problem 33E

Mopeds (small motorcycles with an engine capacity below50cm3 ) are very popular in Europe because of their mobility, ease of operation, and low cost. The article “Procedure to Verify the Maximum Speed of Automatic Transmission Mopeds in Periodic Motor Vehicle Inspections” (?J. of Automobile Engr., ?2008: 1615–1623) described a rolling bench test for determining maximum vehicle speed. A normal distribution with mean value 46.8 km/h and standard deviation 1.75 km/h is postulated. Consider randomly selecting a single such moped. a.? hat is the probability that maximum speed is at most 50 km/h? b.? hat is the probability that maximum speed is at least 48 km/h? c.? ?What is the probability that maximum speed differs from the mean value by at most 1.5 standard deviations?
