Do most of students gain weight when they go to college?

What treatments will be compared?

What is the explanatory variable? What type of variable is this?

What is the response variable? What type of variable is this?

What are your null and alternative hypotheses?

Solution

5) A null hypothesis is a hypothesis that says there is no statistical significance between the two variables in the hypothesis.

An alternative hypothesis, simply, is the inverse, or opposite, of the null hypothesis.

4)

Variables of interest in an experiment (those that are measured or observed) are called response or dependent variables. Other variables in the experiment that affect the response and can be set or measured by the experimenter are called predictor, explanatory, or independent variables.

For example, you might want to determine the recommended baking time for a cake recipe or provide care instructions for a new hybrid plant.

3) An independent variable, sometimes called an experimental or predictor variable, is a variable that is being manipulated in an experiment in order to observe the effect on a dependent variable, sometimes called an outcome variable.
