In the frequency distribution below, the first column (class limits) gives the age ranges (in years) of people who participate in a survey. The second column gives the frequency for each age range. a. Determine the class width. If needed, you can use the space below the table. b. Complete the rest of the frequency distribution. For the relative frequency column, round your answers to 2 decimal places.
