Answer:
A.
Step-by-step explanation:
<u>Conditional probability</u>:-
If E and F are two events in a sample space S and P( F) ≠ 0 , then the probability of 'F' after the event 'E' has occurred, is called the conditional probability of the event of F given E and is denoted by
P(E/F) =
"Police report that 78% of drivers are given a breath test
36% a blood test and 22% both tests
let 'B' be the event of blood test and 'Br' be the event of breath test
The correct answer is C; Dependent variable.
Further explanation:
Researchers are very interested in the dependent variable. This variable is what is being tested and measured during the research in progress. In this case, it is the new energy drink.
The researchers are looking for an effect to occur while changing the independent variable of the case study. There are three main different types of variables used in research studies, they are;
- Independent
- Dependent
- Control
With the athletes doing exercises after consuming the test product, they are seeing if the product does give more energy than if they hadn't of consumed the energy drink.
