|
a. |
r would not change |
|
|
b. |
r would be multiplied by 10 |
|
|
c. |
r would be divided by 100 |
|
|
d. |
r would be multiplied by 100 |

I need help from 9-11.
I calculated 7-8 below.
7)Alcohol Consumption (liters/person/year): 3
Heart disease =
260.56-22.969(3)
= 191.653
8) Alcohol Consumption (liters/person/year): 15
Heart disease =
260.56-22.969(15)
= -83.975
It wouldn’t be appropriate because the heart disease is
in -83.975.

The data of a major referral hospital showed that most patients with ischemic heart disease (IHD) were black American. Based on this, it was concluded that black Americans are at higher risk of IHD compared to other community groups. How would you describe the conclusion? A. Correct, because risk factors for IHD are more common in black African American. B. Incorrect, because no test of statistical significance has been made C. Incorrect, because prevalence is used instead of incidence D....
