A poll found that 35% of adults do not work at all while on summer vacation. In a random sample of 8 adults, let x represent the number who do not work during summer vacation. a. give the value of p for this binomial experiment b. find P(x=4) (Round to four decimal places as needed.) c. Find the probability that 2 or fewer of the 8 adults do not work during summer vacation. P(x ≤ 2) (Round to four decimal places as needed.)
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.
A poll found that 35% of adults do not work at all while on summer vacation. In a random sample of 8 adults, let x represent the number who do not work during summer vacation.
a. give the value of p for this binomial experiment
b. find P(x=4) (Round to four decimal places as needed.)
c. Find the probability that 2 or fewer of the 8 adults do not work during summer vacation.
P(x ≤ 2) (Round to four decimal places as needed.)
