Suppose it is reported that 70 % will vote for candidate A. You think this % is different in your neighborhood, so you decide to randomly sample 181 people and ask them if they will vote for candidate A. Suppose we find from our sample that 170 will vote for candidate A. Give ˆpp^ rounded to five decimal places What is the probability that at least 170 people will vote candidate A? State answer to four decimal places. ?
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.
