Table A. 1 lists random digits between 0 and 9. Assume that an even number is a success and an odd number is a failure. Draw three samples of size 10 and write down the proportion of successes. Make a frequency table with all the sample proportions from the entire class. Compute the mean and variance of all the sample proportions. What do you expect the population 7r to equal? Using 5~ what is the variance of an observation? What is the variance of the mean of 10 observations? How does this compare with the result from the frequency table?
