A manufacturing company produces steel housings for electric

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 s\' coil. It is produced using a 250-ton progressive punch p: with a wipe-down operation that puts 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 widths of the troughs, in inches, collected from a sample of 49 troughs, arc stored in EMU. Construct a percentage histogram and a percentage polygon. Plot a cumulative percentage polygon. What can you conclude about the number of troughs that will meet the company \'s requirements of troughs being between 8.31 and 8.61 inches wide?
