Active is an energy drink that claims to provide physical strength. To test this claim, the producers of Active conducted a study. The company recruited 25 high school athletes and 4 professional football players to participate in the study. The high school athletes were each randomly assigned to drink between 1 and 5 ounces of Active. The professional football players were assigned to drink either 30 or 31 ounces. After waiting 10 minutes they completed as many pull-ups as they could. Here is a scatterplot showing the number of energy drinks consumed and the number of pull ups that were completed by each participant, as well as a line of best fit. Which of the following would increase if the professional football players were removed from the data set? (A) rr (B) r^2r2 (C) the slope (D) the standard deviation of the residuals (E) None of the above.
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.
