A student government organization is interested in estimating the proportion of students who favor a mandatory "pass-fail" grading policy for elective courses. A list of names
and addresses of the 645 students enrolled during the current quarter is available from the registrar's office. Using three-digit random numbers in row 2 of the table of random
numbers and moving across the row from left to right, identify the first 10 students who would be selected using simple random sampling. The three-digit random numbers begin
with 885, 470, and 989.
Step 1
To ensure a truly random selection of 10 students from the list of 645, first assign each student a number between 1 and 645, then use the following row from the random
number table to select the sample of 10 students.

Follow-up Question
Step 2
The three-digit numbers from left to right from the random number table were found to be the following.
885
470 989 695 436 791 150 830
301 041 200 306
375 408 459 283
Since there are only 645 students in the sample, any number greater than 645 from this list cannot be used and will be skipped. The first number in
this list, 885, is greater than the sample size 645, so 885 will not
be used. Thus, the first usable number from the list of random
three-digit numbers is
x.
The full list of 10 three-digit numbers that will be used from a sample of 645 students are as follows. (Enter your answer as a comma-separated list.)
470,436,150,301,041,200,306,375,408,459
