1. Conduct the experiment described in the Scenario with 40 students from your class, adding other people if necessary to bring the total up to 40. What proportion of your sample was righteye dominant?

2. In this activity, you will be taking samples from a population in which 40% have some characteristic in order to see how close the proportions in the samples tend to come to 40%. ,.~.

a. Use a random digit table to simulate taking a sample of size 40 from a population with 40% "successes." Let the digits 0, 1, 2, 3 represent a success and 4, 5, 6, 7, 8, 9 represent a failure. Place a tally mark in a table like the one shown here to represent your result .

Number of successes


















b. Combine your results with other members of your class, repeating the simulation until your class has placed tally marks from 100 different samples in the frequency column of the table.

c. Comparing your proportion from step 1 to the frequency table from step b, is it plausible (has a reasonable chance of being the case) that 40% of the population are right-eye dominant? Explain.
