Histogram Use the frequency distribution from Exercise 1 to construct a histogram.

Exercise 1

Frequency Distribution Use the hand lengths in Exercise 2 to construct a frequency distribution. Use a class width of 10 mm, and use 150 mm as the lower class limit of the first class.

Exercise 2

Designing Gloves An engineer is designing a machine to manufacture gloves and she obtains the following sample of hand lengths (mm) of randomly selected adult males (based on anthropométrie survey data from Gordon, Churchill, et al.):

a. Are exact hand lengths from a population that is discrete or continuous?

b. What is the level of measurement of the hand lengths? (nominal, ordinal, interval, ratio)

Solution 3CRE

From the given information, the frequency distribution for the hand lengths (in millimeters) by taking lower limit of the first class is 150 mm and the class width of 10 mm is

Hand Lengths (millimeters) | Tally Marks | Frequency |

150 - 159 | 1 | |

160 – 169 | - | 0 |

170 – 179 | 2 | |

180... |
