The data represent the time, in minutes, spent reading a political blog in a day. Construct a frequency distribution using 5 classes. In the table, include the midpoints, relative frequencies, and cumulative frequencies. Which class has the greatest frequency and which has the least frequency? C Complete the table, starting with the lowest class limit. (Simplify your answers.) Class Frequency Midpoint 17 "" Which class has the greatest frequency?
