1. Assume the 6360 class portfolio results are:

Class mean return = 8.86

Class standard deviation = 6.16

N=40

Dartboard mean return = 5.87

A. (5 points)Is the mean of the class statistically different than the mean of the dartboard portfolio? In answering this question, state the null hypothesis, compute the appropriate test statistic, and, as a function of the test statistic, state whether the mean of the class is statistically different than the mean of the dartboard portfolio.

B. (5 points) Further, assume that the undergrad investment class (Finance 4050) portfolio results are:

Class mean return = 2.2

Class standard deviation = 3.65

N=25

Is the mean of the 6360 class statistically different than the mean of the 4050 undergrad class? In answering this question, state the null hypothesis, compute the appropriate test statistic, and, as a function of the test statistic, state whether the mean of the 6360 class is statistically different than the mean of the 4050 class.
