Tables and Graphs

1. A transportation museum has a building on both sides of Interstate 64/Highway 40. A walkway across the highway connects the two parts of the museum. At one of the exhibits, radar devices are placed in the walkways so that visitors can clock the speeds of motorists on the highway below. Following are the recorded speeds of motorists on a Tuesday afternoon (4:00 – 4:10).

 83 77 75 74 72 72 69 68 68 68 68 62 62 62 62 62 61 61 61 61 61 61 60 58 58 58 58 58 57 57 57 57 56 55 54 54 54 54 54 53 52 52 52 52 52 47 47 43 40 40

For the data above, construct a frequency table and histogram. Evaluate the graphics. Is the data normally distributed? If not, is it positively or negatively skewed? Is there kurtosis?
