Answer to Problem 2E
Categorical variable:
Gender, Race, Smoker
Quantitative variable:
Age,Systole blood pressure, Level of calcium in the blood
Explanation of Solution
Given:
Gender (female or male); age (years)
Race (Asian, black, white, or other)
Smoker (yes or no)
Systolic blood pressure (millimeters of mercury)
Level of calcium in the blood (micrograms per milliliter)
Calculation:
From the given information we have the following
1.Gender (female or male): categorical variable
2. Age (years):quantitative Variable
3. Race (Asian, black, white or other): categorical variable
4. Smoker (yes or no): categorical variable
5. Systole blood pressure (millimeters of mercury):quantitative variable
6. Level of calcium in the blood (micrograms per milliliter):quantitative Variable
