We continue in this fashion, obtaining the following 12 randomly selected values from the population: 77, 68, 81, 71, 81, 69, 64, 80, 59, 61, 76, 90

Work Step by Step

A random sample of N=12 digits is drawn from the population of 38 data values by using the table of random digits on the first page, columns 10-11. The first random number of 65 is unsuitable because it is too large. The second random number of 18 is used to choose the 18th piece of data for the sample, which is the value 77. The next usable random number is 11. We choose the 11th data value from the population, which is 68.
