Question

One of your friends is reading a newspaper article, which notes that, in rats, a positive significant relationship exists between sugar consumption and obesity. The more sugar a rat consumes, the higher its overall body mass. Your friend asks you what it means that the results of this experiment were statistically significant. What do you tell him?
1) The fact that rats that consume more sugar have higher body masses could be due to chance, or could not be due to chance. Both possibilities are equally likely.
2) The sample size of rats in this study was remarkably small, but no more studies are needed to evaluate the relationship between rat sugar consumption and body mass.
3) The fact that rats that consume more sugar have higher body masses is not due to chance.
4) The fact that rats that consume more sugar have higher body masses is purely due to chance.

Answer 1

Answer:

3) The fact that rats that consume more sugar have higher body masses is not due to chance.

Explanation:

A diet high in added sugars, such as sweetened drinks, snacks, pastries and sugar cereals, is a factor that contributes in excess weight gain and medical problems, including obesity. It doesn't happen by chance as there is a direct correlation between them.
