Question

6 - #7968

Your answer: B was incorrect. The correct answer was D)

Independence and Objectivity.

Using compensating trades to cover trading errors make it appear that the advisor is placing his or her needs ahead of the client痴 best interest. This is a violation of the Standard concerning Independence and Objectivity.

Question

7 - #7982

Your answer: B was incorrect. The correct answer was C)

paid must be reasonable in relation to the research and execution services provided.

Commissions paid must be reasonable in relation to the research and execution services provided. This does not imply that trades are always directed to the lowest cost broker.

Question

8 - #8609

Your answer: B was incorrect. The correct answer was A)

The assumption of linear regression is that the residuals are heteroskedastic.

The assumption of regression is that the residuals are homoskedastic (i.e., the residuals are drawn from the same distribution).

Question

9 - #8659

Your answer: B was correct!

Y = 2.83 + (1.5)(2)
= 2.83 + 3
= 5.83

Question

10 - #8752

Your answer: B was incorrect. The correct answer was A)

H0: σA2 = σB2 versus Ha: σA2 ≠ σB2.

In hypothesis testing anytime we want to know if something is different from something else this is a two tailed test.  A two tailed test always involves a null hypothesis containing an equals sign (=) and the alternative hypothesis will always contain a not equals to sign (≠).
