A St. Louis–based shipping company recently selected a random sample of 49 airplane weight slips for crates shipped from an automobile parts supplier. The weights, measured in pounds, for the sampled crates are as follows:

89 83 97 101 86 89 86 91 84 89 87 93 86 90 86 92 92 88 88 92 86 93 80 93 77 98 94 95 94 88 95 87 99 98 90 91 87 89 89 96 88 94 95 79 94 86 92 94 85

a. Create a data array of the weights.

b. Develop a frequency distribution using five classes having equal widths.

c. Develop a histogram from the frequency distribution you created in part b.

d. Develop a relative frequency and a cumulative relative frequency distribution for the weights using the same five classes created in part

b. What percent of the sampled crates have weights greater than 96 pounds?
