Question: Participants in a diet-exercise program were asked to record their weight loss, in pounds (lb), over a two-month period. The results were as follows:

27 5 18 14

21 15 12 23

12 8 20 16

13 18 19 22

29 16 24 18

Construct a frequency distribution for these data using a lower limit for the first class of 5 and a class width of 5. Indicate the class limits, boundaries, midpoints, frequencies and cumulative frequencies.

(Note: as this data does not contain fractional values, do not use the 'less than' method for writing the classes.)
