a. Make a frequency distribution of this data. Use 5 classes (aka bins) with a class
width of 4, and let the first class have a lower limit of 1. Include a column
for frequency, relative frequency and cumulative frequency. Write your relative
frequency as simplified fractions or decimals (rounded to three places, if needed).
b. Describe the shape of the distribution
