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:

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?
