Question
One operation of a mill is to cut pieces of steel into parts. The steel is cut with a diamond saw and requires the resulting parts to be within .005 inches of the length specified by the automobile company. The data are collected from a sample of 65 steel parts and stored in the data table link below. 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 0.0009, represents a steel part that is 0.0009 inch shorter than the specified length. Complete parts a) and b) below Click the icon to view the data a. Construct a percentage histogram. Select the histogram that represents the data A. c. 50 50 30 20 -0.000.000.003 0.000.000.003 0.008.000.003 Difference (in.) Difference (in.) Difference (in.) b. Is the steel mill doing a good job meeting the requirements set by the automobile company? Explain A. No, the majority of the parts are greater than the specified length, indicating a bias in the machine's cutting pattern. Also some of the values are outside the O B. No, the majority of the parts are less than the specified length, indicating a bias in the machine's cutting pattern. Also some of the values are outside the range ° C. Yes, the majority of the parts are very close to specified length, and all values are within the range of acceptable cutting error range of acceptable cutting error. of acceptable cutting error. No, the majority of the parts are very close to specified length, however not all values are within the range of acceptable cutting error O D.Explanation / Answer
a) for histogram : option A is correct
b)
option C is crrect ; yes majority of the parts are very close to the specified length....
