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

In an experiment to study the relationship of hypertension and smoking habits, the following data are collected for 180 individuals:

Nonsmokers 21 H, 48 NH

Moderate Smokers 36 H, 26 NH

Heavy Smokers 30 h, 19 NH

Where H and NH stands for Hypertension and NonHypertension, respectively. If one of these individuals is selected at random find the probability that the person is

(a) experiencing hypertension, giving that the person is a heavy smoker

(b) a nonsmoker, giving that the person is experiencing no hypertension

A random experiment was run 23 times with groups of 24 mice. Each time the experiment was run, 4 mice were initially infected with a disease; the remaining mice were susceptible to contracting the disease.

There are declining levels of cooperation among persons contacted in surveys and this brings concerns to pollsters. A pollster contacts 92 people in the 18-21 age bracket and finds that 78 of them respond and 14 refuse to respond. When 276 people in the 22-29 age bracket are contacted, 259 respond and 17 refuse to respond. Assume that 1 of the 368 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who agreed to respond. Report the answer as a percent rounded to one decimal place accuracy.

Do cat owners sleep better than those without cats? To help answer this question, a cat enthusiast obtained a random sample of 500 Canadians, each of whom answered two questions: 1. do you have a cat? (yes or no), 2. How well do you sleep? (good, neutral, bad). The dataset “CatSleep.xlsx” contains her findings. Find the probability that a randomly selected Canadian is a bad sleeper and a cat owner. Find the probability that a randomly selected Canadian is a neutral sleeper or a cat owner. Find the probability that a randomly selected non-cat owner is a bad sleeper. That is, find the probability that a randomly selected Canadian is a bad sleeper, given they are not a cat owner Can you handwrite the solution?
