A distribution company in Alberta surveyed 55 of its midlevel managers. The survey obtained the ages of these managers, which later were organized into the frequency distribution shown. Determine the class midpoint, relative frequency, and cumulative frequency for these data. Class Interval Frequency 20-under 25 25-under 30 6 30-under 35 6 35-under 40 14 40-under 45 15 45-under 50 7 (Round relative frequency to 4 decimal places, e.g. 0.2345.) Class Frequency Class Midpoint Relative Frequency Cummulative Frequency Interval 20 - 25 7 25 - 30 30 - 35 6 35 - 40 14 40 - 45 15 45 - 50 7 Total
