A manufacturing company produces steel housings

A manufacturing company produces steel housings for electrical equipment. The main component part of the housing is a steel trough that is made out of a 14-gauge steel coil. It is produced using a 250-ton progressive punch press with a wipe-down operation, putting two 90-degree forms in the flat steel to make the trough. The distance from one side of the form to the other is critical because of weatherproofing in outdoor applications. The company requires that the width of the trough be between 8.31 inches and 8.61 inches. The data file trough.xls contains the widths of the troughs, in inches, for a sample of n = 49:

a. Calculate the mean, median, range, and standard deviation for the width. Interpret these measures of central tendency and variability.

b. List the five-number summary.

c. Construct a box-and-whisker plot and describe its shape.

d. What can you conclude about the number of troughs that will meet the company s requirement of troughs being between 8.31 and 8.61 inches wide?
