Answer to Problem 77STP

It is an observational study.

Explanation of Solution

Given:

It is given in the question that there are 100 students half of them have part time jobs and also compare their grades.

Since, in this case the students have to see the grades of the part time job students just only observe.

It is observing an already formed group. It has not changing anything, just observing.

Hence, it is an observational study .
