Differences in weight

Question

Susan suspected that her pet hamster was chubbier than her roommate's hamster. She weighed both critters and found out that her hamster weighed 250g, whereas her roommate's hamster weighed 160g. Can she conclude that her hamster is heavier than her roommate's hamster? Why?

Answer 1

Please remove these old questions. As for Susan, both her hamsters are by now dead. Question is moot.

By the way, no statistics are needed for the question. Each hamster was weighed on a (fair) scale. One had a value x₁ of 250g and the other had a value of x₂ = 160. x₁>x₂ Q.E.D.
