The mean increase for a two-year period for the income funds is $\$900$.

For the growth funds, the mean increase is $\$875$.

Income funds have a population standard deviation of $\$75$.

Growth funds have a population standard deviation of $\$65$.

The financial planner would like to know if there is a difference in the mean yields of the two funds.

This is an example of:
