Expert Solution
Null Hypothesis

The null hypothesis is a statistical theory that states that there is no statistical relationship or significance between two sets of observed data and measured events in a given single observed variable. The null hypothesis states that two options are identical in inferential statistics. The null hypothesis states that the observed discrepancy is entirely attributable to chance. The likelihood of the null hypothesis being true can be calculated using statistical testing.

A null hypothesis is something like, "Hyperactivity is unrelated to eating sugar." If the hypothesis is evaluated and proved to be untrue using statistics, there may be a link between hyperactivity and sugar consumption.
