Consider the Claim That 60% of the Members of a Population

question 7

Multiple Choice

Consider the claim that 60% of the members of a population of bacteria have a plasmid conferring antibiotic resistance. If we collected some random bacterial samples and the P-value of a binomial test was 0.15, what would our conclusion be?

• A) We fail to reject the null hypothesis and therefore conclude that the true proportion of bacteria with resistance plasmids differs from 60%.
• B) We fail to reject the null hypothesis and therefore conclude that the true proportion of bacteria with resistance plasmids does not differ from 60%.
• C) We reject the null hypothesis and therefore conclude that the true proportion of bacteria with resistance plasmids differs from 60%.
• D) We reject the null hypothesis and therefore conclude that the true proportion of bacteria with resistance plasmids does not differ from 60%.
