In each of Exercises 2.140-2.149, we have provided a graphical display of a data set. For each exercise, state whether the distribution is (roughly) symmetric, right skewed, or left skewed. 2.141 Clocking the Cheetah. 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 on- line 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. Follow- ing is a frequency histogram for the speeds, in miles per hour, for a sample of 35 cheetahs. 2.146 Adjusted Gross Incomes. The Internal Revenue Service (IRS) publishes data on adjusted gross incomes in the document Statistics of Income, Individual Income Tax Returns.
