Refer to the accompanying data set and use the 30 screw lengths to construct a frequency distribution. Begin with a lower class limit of 0.470 in, and use a class width of 0.010 in. The screws were labeled as having a length of 1 divided by 2 in. Does the frequency distribution appear to be consistent with the label? Why or why not?

    A) Total frequency = 30

    B) Yes, the distribution is consistent with the label because the frequencies are greatest when the lengths are closest to the labeled size of 1/2 inches which is 0.5 inches.

    Step-by-step explanation:

    Since the class limit width is 0.010 from the question, we arrive at;

    Class Limits Frequency

    Length (Inches)

    0.470 - 0.479 3

    0.480 - 0. 489 5

    0.490 - 0.499 9

    0.500 - 0.509 12

    0.510 - 0.519 1

    Adding the frequency, total = 30
