1. One operation of a mill is to cut pieces of steel into parts that will later be used as the frame for front seats in an automobile. The steel is cut with a diamond saw and requires the result-ing parts to be within {0.005 inch of the length specified by the automobile company. Data are collected from a sample of 100 steel parts and stored in Steel . The measurement reported is the difference in inches between the actual length of the steel part, as measured by a laser measurement device, and the specified length of the steel part. For example, the first value, -0.002, represents a steel part that is 0.002 inch shorter than the speci-fied length.

a. Construct a frequency distribution and a percentage distribution.

b. Construct a cumulative percentage distribution.

c. Is the steel mill doing a good job meeting the requirements set by the automobile company? Explain
