Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 79 people in the 18-21 age bracket and finds that 67 of them respond and 12 refuse to respond. When 276 people in the 22-29 age bracket are contacted, 249 respond and 27 refuse to respond. Assume that 1 of the 355 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who responds. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol. P(22-29 or responds) = (Hint: It might be helpful to organize the data into a table first.)

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.
