Hi, I think I got the question but not so sure.

The question is:

A systematic random sample is to be chosen of size 5, from a class of 30 numbered 01-30. To determine the starting point, a die is thrown and comes up 1. List the lables of the students who will be included in the sample

I tried doing.

pop size/ sample size= 30/5 = 6

then i did 01 +06 = 07 and so on to determine whos in the sample, but by going up in intervals of 6, i only get 07,13,19,25.

Am i doing anything wrong, why do i only get 4 people instead of 5?

Count the first "1" also.
