Problem 29

Arm length How long is your arm compared with your hand size? Put your right thumb at your left shoulder bone, stretch your hand open wide, and extend your hand down your arm. Put your thumb at the place where your little finger is, and extend down the arm again. Repeat this a third time. Now your little finger will probably have reached the back of your left hand. If the fourth hand width goes past the end of your middle finger, turn your hand sideways and count finger widths to get there. a) How many hand and finger widths is your arm? b) Suppose you repeat your measurement 10 times and average your results. What parameter would this average estimate? What is the population? c) Suppose you now collect arm lengths measured in this way from 9 friends and average these 10 measurements. What is the population now? What parameter would this average estimate? d) Do you think these 10 arm lengths are likely to be representative of the population of arm lengths in your community? In the country? Why or why not?

Chapter 2 Section 2.2  Frequency Distribution: Shows how data are parted within different categories(classes)  Lower class Limits: the smallest values in the different classes  Ex: Class interval: 10­19; 26­30; 80­100 Lower Class Limits: 10, 26, and 80  Upper class Limits: the largest values in the different classes.  Ex: Class Interval: 10­19; 26­30; 80­100 Upper Class Limits: 19, 30, and 100  Class Boundaries: The values that are used to separate the classes, not including the gaps created by class limits.  Ex: Class Interval: 10­19; 20­30; 80­100 Class Boundaries: 19+20/2 = 19.5  Class midpoints: the values in the middle o
