9. When Olympic athletes are tested for illegal drug use (i.e., doping), the result of a single test are used to ban the athlete from competition. In a population of 1,000 athletes, suppose 120 are illegally using testosterone. Of the users, suppose 66 would test positive for testosterone. Of the nonusers, suppose 11 would test positive. (a)Given that the athlete is a nonuser, find the probability that a drug test for testosterone will yield a negative result. (b)If an athlete tests positive for testosterone, find the probability that the athlete is really doping.
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.
