The NBA wants to determine how many of its players would be in favor of shortening the length of the regular season. They send out a survey to 72 players and find that 54 (75%) are in favor of reducing the length of the season. Assume all assumptions are met, we now want to create a 90% Confidence Interval for the proportion of players in favor of reducing the length of the season. (0.746, 0.754) (0.705, 0.795) (0.666, 0.834) (0.714, 0.786) (0.622, 0.878)
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.
