Given the following regression equation, what can be said about the relationship between the infant mortality rate and GDP per capita?
GDP per capita = $18499.41 - $317.87 infant mortality
| A. |
It's positive |
|
| B. |
No relationship exists |
|
| C. |
Can't say for certain |
|
| D. |
It's negative |
Homework Answers
Sol:
since slope=-317.87
There exists a negative relationship between GDP per capita and infant mortality
As infant mortality increases,GDP per capita decreases
and as infant mortality decreases,GDP per capita increases
ANSWER
| D. |
It's negative |

What can be said about the relationship between the significance and the effect size of a hypothesis test? Group of answer choices The significance of a test is not determined by the effect size alone. A significant test result leads to a large effect size while a non-significant test result leads to a small effect size. The effect size is determined by the alpha level while the significance of a test is not. The effect size is always the same...
