Exercise 3.12 of the textbook

Question

a. The circles are labeled 00, 01, ... , 99. Use line 101 of Table A to draw an SRS of

size 4. What is the proportion p of the people in your sample who favor a state

constitutional amendment?

b. Take 9 more SRSs of size 4 (10 in all), using lines 102 to 110 of Table A, a different

line for each sample. You now have 10 values of the sample proportion p. Write

down the 10 values you should now have of the sample proportion p.

c. Because your samples have only 4 people, the only values p can take are 0/4, 1/4,

2/4, 3/4, and 4/4. That is, p is always 0, 0.25, 0.5, 0.75, or 1. Mark these numbers on

a line and make a histogram of your 10 results by putting a bar above each number

to show how many samples had that outcome.
