A college registrar completes a survey of classrooms on campus in order to find out how many usable seats there are in each one. Make a grouped frequency distribution for her data, using an interval width of 20 and an apparent lower limit of 10 for the bottom interval. Report midpoint, frequency, cumulative frequency, percentage, and cumulative percentage. Here are the data the registrar collected: 12, 26, 18, 17, 102, 20, 35, 46, 50, 28, 29, 53, 75, 30, 37, 45, 58, 43, 42, 36, 50, 60, 55, 45, 40, 23, 28, 38, 39, 40, 50, 60, 45, 36, 28, 40, 54, 62, 38, 58, and 24.
