Question
Refer to the accompanying data set and use the 30 screw lengths to construct a frequency distribution. Begin with a lower class limit of
1.220
in, and use a class width of 0.010 in. The screws were labeled as having a length of
1 1 divided by 4 in.
Does the frequency distribution appear to be consistent with the label? Why or why not?

Does the frequency distribution appear to be consistent with the label?
A.
Yes, because the frequencies are greatest in the classes closest to the labeled size.
B.
No, because the screw lengths are off by as much as 0.03 in.
C.
No, because the class frequencies are not consistent.
D.
Yes, because the screw lengths are no more than .03 in off the labeled
