Basic Question 0 of 10
An analyst is currently reviewing the following regression analysis:
B. Since the calculated t-statistic of 2.88 exceeds the critical t-statistic, the null hypothesis is rejected.
C. Since the calculated t-statistic of 6.88 falls within the critical t-statistic, the null hypothesis is accepted.
At a significance level of 5%, which of the following statements would best reflect the null hypothesis that coefficient of the first independent variable is equal to 1.0?
A. Since the calculated t-statistic exceeds the critical t-statistic of 1.68, the null hypothesis is rejected.
B. Since the calculated t-statistic of 2.88 exceeds the critical t-statistic, the null hypothesis is rejected.
C. Since the calculated t-statistic of 6.88 falls within the critical t-statistic, the null hypothesis is accepted.

| grewei | Wouldn't the critical t-statistic be between 2.000 and 2.021? The answer (B) is the same but I come up with a different critical t-statistic. |
| noonah | Should not we use the F-statistic since it is a multiple regression? |
| noonah | Oops, discard above comment. We can use the t-statistic since we are testing the significance of only one indep. variable, rather than ALL of them. |
| aruffo | What formula is being used to calculate the t-test here? |
| awbronson | @aruffo me thinks... {B(hat) - B)} / Stand Error of B(hat) .... pg 298 in print CFA curriculum |
I am using your study notes and I know of at least 5 other friends of mine who used it and passed the exam last Dec. Keep up your great work!
