An advertisement claims that chewing NoCav gum reduces cavities. To test the claim, you conduct a study in which 100 participants who chew the gum are compared to the national average for cavities found. To test the research hypothesis that the mean number of cavities for NoCav chewers is below the national average, you use a significance level of .05. Given a resulting p-value is .08, how would you react to the advertised claim?
A. Conclude that the gum reduces cavities.
B. Conclude that the gum might reduce cavities.
C. Conclude that the gum does not reduce cavities.
D. There is insufficient evidence to conclude that the gum reduces cavities.
