Jimmy's Electric Products assembles components for cell phones. For the last 10 days Mark has averaged 9 rejects per day, with a std. dev. of 2 rejects per day, while Debbie has averaged 8.5 rejects per day with a std. dev. of 1.5 rejects per day, over the same period. At the 0.05 significance level, can we conclude that there is more variation in the number of rejects per day attributed to Mark?

Mark's daily variation is no more than Debbie's variation.

There is not enough information to answer the question, the formula requires knowing the population standard deviation for Mark and Debbie, and we were not given this information.
