Lines at the Department of Motor Vehicles are so long! A supervisor decided to conduct a study on the number of people standing in line. At the beginning of each hour for an entire week, the supervisor counted the number of people in line and recorded the number. At the end of the week, the supervisor made the frequency table below. Note that the first column shows the number of people in line at the beginning of the hour. The second column shows the number of times that length of line occurred in the 40 observations.
