For each problem, a) find the difference between the two sample proportions. b) use Confidence Interval for the Difference in Proportions Calculator - Statology to find a 90%, 95% and 99% confidence interval for true difference between the two proportions. c) Determine whether zero is a possible difference or not. If so, zero is in which confidence level? Problem 1: The Centers for Disease Control and Prevention reported a survey of randomly selected Americans age 65 and older, which found that 535 of 1060 women and 411 of 1012 men suffered from some form of arthritis.|

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.
