Expert Solution

Answer to Problem 1CRE

The probability is 0.875.

Explanation of Solution

Given:

A study has been conducted to check if obese people are more likely to die in comparison of people who weigh less. A possible confounder is that the obese people are inactive and lazy

Calculation:

In this case, mortality rate is the response variable because it is dependent on the weight of the people. Thus, it could be conclude that mortality rate is a response variable and weight is an explanatory variable.

b.

To determine

To explain: Whether it could be concluded that weight is causing the increase in risk of death

b.
