Concept explainers

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.

Enterococci are bacteria that cause blood infections in hospitalized patients. One antibiotic used to battle enterococci is vancomycin. A study by the Federal Centers for Disease Control and Prevention revealed that 3% of all enerococci isolated in hospitals nationwide were resistant to vancomycin.

Age Untreated Treated People Disease Disease per 100K People Disease Disease per 100K young 5,000,000 40 0.8 5,000,000 20 0.4 old 1,000,000 60 6.0 10,000,000 300 3.0 Table 1: Disease rates based on age and treatment status. (a) Define the following events and compute four conditional probabilities of contract- ing the disease based on a person’s age and based on their treatment status. The events are D:= contracting the disease, Y := young, O:= old, T:= treated, and U:=untreated. Note that O = Y c, and similarly for T and U. Now, calculate 4 probabilities like P(D|T, Y ) for each possibility. (b) What is the probability of contracting the disease if you are treated? Untreated? (c) Based on…
