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.

The total body surface area, or BSA, of a human is difficult to calculate. There are various models that estimate BSA based on a person's weight and height. One simpler model is where w= weight in kg and h = height in cm. Round your answer to the nearest cm. a. Using this model, estimate the height of a person who weighs 74 kg and whose BSA is 1.9. h = Number cm Round your answer to the nearest kg. W= BSA = b.

The manager has gathered data from a group of employees to evaluate the effects of sleep and sickness. The manager asked employees to record the total number of hours of sleep they had over 10 working days in two weeks and compared it to the number of sick days that each took over those 10 days. Sick Days Total hours of sleep 0 80 2 40 1 60 0 70 3 50 2 90 4 35 1 68 0 72 2 55 The manager wonders if a non-linear model is a better relationship between the variables.
