Quizplus · Accepted Answer

The null hypothesis (H0) is a statement of no effect or no difference, which in this case would be the claim that at least 80% of dentists prefer the gum, hence P ≥ 0.80. The alternative hypothesis (H1) is what the research aims to support, which is that less than 80% of dentists prefer the gum, hence P < 0.80.
