Exam MAS-I Practice Question 170
Study guide: Exam MAS-I
Four analysts each test whether a regression coefficient \beta is zero, using the t-statistic \hat\beta/\text{SE}(\hat\beta):
- (A) A simple linear regression on 7 territories gives
t = 2.7; the alternative is\beta \ne 0. - (B) A regression with an intercept and 3 predictors on 64 policies gives
t = 2.45; the alternative is\beta \ne 0. - (C) A regression with an intercept and 3 predictors on 64 policies gives
t = 2.45; the alternative is\beta > 0. - (D) A simple linear regression on 7 territories gives
t = 2.1; the alternative is\beta \ne 0.
Rows of the t table (two-sided tail areas):
df |
0.20 | 0.10 | 0.05 | 0.02 | 0.01 |
|---|---|---|---|---|---|
| 5 | 1.476 | 2.015 | 2.571 | 3.365 | 4.032 |
| 60 | 1.296 | 1.671 | 2.000 | 2.390 | 2.660 |
Order the four tests by p-value, from smallest to largest. Enter the letters with no spaces, e.g. ABCD.
