first let's define null and alternative hypothesis
null hypothesis is a negative hypothesis in which it states that there is no relationship between 2 variables
hyperactivity is unrelated to eating sugar
alternative hypothesis is a hypothesis where it is positive and states that there is a relationship between 2 variables
consuming of sugar or foods containing sugar may cause diabetes and/or cavities
Not so long ago, people believed that the world was flat.
There are two options for a decision. They are “reject H 0” if the sample information favors the alternative hypothesis or “do not reject H 0” or “decline to reject H 0” if the sample information is insufficient to reject the null hypothesis.
