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.

Question

Testing for a disease can be made more efficient by combining samples. If the samples from four people are combined and
the mixture tests negative, then all four samples are negative. On the other hand, one positive sample will always test
positive, no matter how many negative samples it is mixed with. Assuming the probability of a single sample testing positive
is 0.15, find the probability of a positive result for four samples combined into one mixture. Is the probability low enough so
that further testing of the individual samples is rarely necessary?
The probability of a positive test result is
(Round to three decimal places as needed.)
Is the probability low enough so that further testing of the individual samples is rarely necessary?
A. The probability is low, so further testing will be necessary for all of the combined mixtures.
B. The probability is not low, so further testing will not be necessary for any of the mixtures.
C. The probability is low, so further testing of the individual samples will be a rarely necessary event.
D. The probability is not low, so further testing of the individual samples will frequently be a necessary event.

A survey of heads of households showed the percentage of those who asked for a raise and the percentage of those who asked for a raise and the percentage who got one. Accordig to the survey, of the omen interviwed 28% asked for a raise, and of those women who asked for a raise, 45% recieved the raise. If a woman is selected at random from the survey population of women, find the following probabilites. (To three decimal places) P(woman asked for a raise) P(woman recieved raise, given she asked for one) P(woman asked for raise and recieved raise)
