The probability of a randomly selected adult in one country being infected with a certain virus is 0.003. In tests for the virus, blood samples from 11 people are combined. What is the probability that the combined sample tests positive for the virus? Is it unlikely for such a combined sample to test positive? Note that the combined sample tests positive if at least one person has the virus. The probability that the combined sample will test positive is Is it unlikely for such a combined sample to test positive? A. It is not unlikely for such a combined sample to test positive, because the probability that the combined sample will test positive is greater than 0.05. B. It is unlikely for such a combined sample to test positive, because the probability that the combined sample will test positive is less than or equal to than 0.05. C. It is unlikely for such a combined sample to test positive, because the probability that the combined sample will test positive is greater than 0.05. D. It is not unlikely for such a combined sample to test positive, because the probability that the combined sample will test positive is less than or equal to than 0.05.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
