Refer to the speed data given in Exercise 2.61.
In exercise 2.61.
The cheetah (Acinonyx jubatus) is the fastest land mammal and is highly specialized to run down prey. The cheetah often exceeds speeds of 60 mph and, according to the online document "Cheetah Conservation in Southern Africa" (Trade & Environment Database (TED) Case Studies, Vol. 8, No. 2) by J. Urbaniak, the cheetah is capable of speeds up to 72 mph. The following table gives the speeds, in miles per hour, over 1/4 mile for 35 cheetahs. Use cutpoint grouping with 52 as the first cutpoint and classes of equal width 2.

a. Construct a table similar to Table 2.14 for the data, based on the classes specified in Exercise 2.61. Interpret your results.
b. Construct an ogive for the data.
