Question

1. Wildlife biologists recorded the weights of grizzly bears in 2 different populations. The normal curves represent the weights of the bears in Population A and the weights of bears in Population B. Population A Population B Weight of Bears a. Which population has the greater mean weight? Explain your reasoning.

Answer 1

Population B has the greater mean weight. This can be seen from the fact that the curve of population B is located to the right of the curve of population A, this means that the mean is greater since the horizontal line represents the weight of the bears and the positive sign is to the right according to the line.
