Before 2012, National Football League (NFL) football games that were tied at the end of regulation time continued after a coin toss. The team that won the coin toss could choose to receive the ball or kick the ball. A whopping 98.1% of teams that won the coin toss chose to receive the ball. Between 1974 and 2011, there were 460 overtime games that did not end in a tie. Among those 460 games that decided were in overtime, 252 were won by the same team that won the overtime toss. Assume that wins and losses are equally likely, so both teams have the same 0.5 chance of winning the game in overtime. a)Find the meanand standard deviationfor the number of wins in groups of 460 games. ?=?? ?= √???
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.
