It has been estimated that only about 26% of residents in Ventura County have adequate earthquake supplies. Suppose you randomly survey 27 residents in the County. Let X be the number of residents who have adequate earthquake supplies. What is the distribution of X? X ~ Please show the following answers to 4 decimal places. What is the probability that less than 12 residents who have adequate earthquake supplies in this survey? What is the probability that between 5 and 13 (including 5 and 13) residents who have adequate earthquake supplies in this survey?
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.
