A task force to encourage car pooling did a study of one-way commuting distances (in miles) of workers in the downtown Dallas area. A random sample of 60 of these workers was taken. The commuting distances of the workers in the sample are given in the following grouped frequency distribution: Class limit (distance in miles) Frequency 1- 10 18 11 - 20 24 21 - 30 10 31 - 40 4 41 - 50 How many of these sample workers commute more than 20.5 miles?
