First Avenue is in desperate need of repaving. The county road commission would like to survey the people who live along this road. They have a list available of all 176 household addresses along First Avenue with the addresses listed in numerical order by address. Explain an efficient labeling scheme for taking a simple random sample of 20 household addresses.

Question 2

The next three questions are based on the following row of digits from a random number table. Use these digits to select a random sample following steps 1 through 4 in the text. 00157 37071 79553 31062 42411 79371 25506 69135 Suppose that a group of 20 students are numbered from 01 to 20 . Draw a simple random sample of 5 students by starting with the digit 01 from the first string of digits 00157 . Which 5 students would be selected? (Do not use the more efficient method of, for instance, choosing number 1 if 21, 41, 61, or 81 is the random number.)
