Answer:

The best value of k for the worker to use is 30.

Explanation:

Sample of 120 jars from a set of 3,600.

If the worker will select every kth jar, what is the best value of k for the worker to use?

The best case would be starting at 0 and ending at 3600, finding 120 values, which means that k is given by the division of 3600 by 120. So


k = (3600)/(120) = (360)/(12) = 30

The best value of k for the worker to use is 30.
