Friday the 6th 6 8 11 12 6   Friday the 13th 11 15 11 12 12 In this​ example, μd is the mean value of the differences d for the population of all pairs of​ data, where each individual difference d is defined as the number of hospital admissions on Friday the 6th minus the number of hospital admissions on Friday the 13th. Find the​ 95% confidence interval.     nothing<μd<   nothing ​(Round to two decimal places as​ needed.) Based on the confidence​ interval, can one reject the claim that when the 13th day of a month falls on a​ Friday, the numbers of hospital admissions from motor vehicle crashes are not​ affected?   A. Yes​, because the confidence interval does not include zero.   B. Yes​, because the confidence interval includes zero.   C. No​, because the confidence interval does not include zero.   D. No​, because the confidence interval includes zero.

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.
