Question: The Cheetah is the fastest land mammal on earth and is highly specialized to run down prey. The cheetah often exceeds speeds of 60 mph and has been clocked at speeds of more than 70 mph. The following table gives the speeds of a cheetah in miles per hour, over a quarter mile for 35 cheetahs.

57.3, 57.5, 59.0, 56.5, 61.3, 57.6, 59.2, 65.0, 60.1, 59.7, 62.6, 52.6, 60.7, 62.3, 65.2, 54,8, 55.4, 55.5, 57.8, 58.7, 57.8, 60.9, 75.3, 60.6, 58.1, 55.9, 61.6, 59.6, 59.8, 63.4, 54.7, 60.2, 52.4, 58.9, 66.0

Use 52 as the first lower boundary for the first class and made all the classes of equal width of 2 to construct a grouped-data table, find the frequency, relative frequency, draw the histogram and the frequency polygon.
