What side does the critical region go on in a 1tailed associated test?
I'm trying to answer if the average work time of a student is 60 minutes per day. I have my sample of 40 students to ensure relative normality--on the test of significance, a 1 tailed associative test, what side of the distribution should my critical value be on?

If you want to know if the average work time is equal to 60 mins then a 2 tailed test is used.
If you are looking at if the average work time is 'less than 60' mins or 'greater than 60 mins' then we are talking one tail.
