2.2.27 Question Help * Refer to the accompanying data set and use the 30 screw lengths to construct a frequency distribution. Begin with a lower class limit of 3.720 in, and use a class width of 0.010 in. The screws were labeled as havinga length of 3 3/4 in. Does the frequency distribution appear to be consistent with the label? Why or why not? Click on icon to view the data. 3.720 3.729 3.730 3.739 3.740 3.749 3.750 3.759 3.760 3.769 10 12 Type integers or decimals rounded to the nearest thousandth as needed.) Does the frequency distribution appear to be consistent with the label? A. No, because the class frequencies are not consistent. B. Yes, because the frequencies are greatest in the classes closest to the labeled size. C. Yes, because the screw lengths are no more than .03 in off the labeled size. O D. No, because the screw lengths are off by as much as 0.03 in. Click to select your answer and then click Check Answer.
