Question 1070716: I do not know how to use a random digit table. If I can submit this problem and see how it is worked out, I think I can get by.
California area codes, are
530 707 916 209 415 925 510 650 408 831 805 559 760
661 818 213 626 323 562 709 310 949 909 858 619
Another California survey does not call numbers in all area codes but starts with an SRS of 10 area codes. Choose such an SRS. Use the random digits table and start at line 122. Label the area codes from left to right from 01 to 25.

Answer by rothauserc(4718)   (Show Source):
You can put this solution on YOUR website! Your sample size is 10 area codes from the population of 25 CA area codes
:
You need to determine if you are to sample with replacement or without replacement, that is
:
If a population element can be selected more than one time, we are sampling with replacement. When a population element can be selected only one time, we are sampling without replacement.
:
You have a random digit table
:
The population size is 25, which is between 10 and 100, so we can use two digit labels for this population.
:
Then start at line 122 in your table and write the random digits in groups of two. Use these groups of two to select the 10 CA area codes from your population list of 25.
;
Note discard a group of two digits that is not in the range 01 to 25 inclusive
