Select the correct answer from each drop-down menu. In an experiment, a scientist decides to study the effect of exercise on cholesterol levels in people. He studies two set of people-those who exercise every day for an hour and those who don't exercise at all. In this case the statement that people who exercise for an hour may have lower cholesterol levels is square 1. To test this statement the scientist would measure cholesterol levels in exercisers and non- exercisers. The cholesterol levels would be a dependent variable square a dependent variable an independent variable

Answer

### dependent variable \( \checkmark \) an independent variable

Explain

## Step1: Identify the hypothesis<br />### The hypothesis is the initial statement that posits a potential relationship between two variables. In this case, the hypothesis is that regular exercise may lead to lower cholesterol levels in people. <br /><br />## Step2: Identify the independent variable<br />### The independent variable is the one that is manipulated or categorized to observe its effect on the dependent variable. Here, the independent variable is whether the participants exercise or not.<br /><br />## Step3: Identify the dependent variable<br />### The dependent variable is the outcome or what is measured in the experiment. In this case, cholesterol levels are measured to see the effect of the exercise, making it the dependent variable.
