A

Ans. #4

FALSE

Ans. #5

Since F2, 18, 0.05 = 3.55 and F = 5.193, we reject H0 at  = 0.05 and conclude that there is sufficient statistical evidence that there is a difference between at least two of the three exam forms.

Ans. #6

A beta value equal to 1.0 means that the specific stock will match market movements, a beta less than 1.0 indicates that the stock is less volatile than the market, and a beta greater than 1.0 indicates that the stock has greater variance than the market. Thus, stocks with large beta values are riskier than those with lower beta values. Beta values can be calculated by developing a regression model of a particular stock's returns (the dependent variable) against the average market returns (the independent variable).

Ans. #7

FALSE
