Suppose that you randomly selected 21 adults. If 23% of the population are smokers, what is the probability that a) all 21 are not smokers? Round this probability to four decimal places. b) exactly 6 smoke? Round this probability to four decimal places. c) exactly 5 smoke? Round this probability 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.
Suppose that you randomly selected 21 adults. If 23% of the population are smokers, what is the
a) all 21 are not smokers? Round this probability to four decimal places.
b) exactly 6 smoke? Round this probability to four decimal places.
c) exactly 5 smoke? Round this probability to four decimal places.
d) at least 6 smoke? Round this probability to four decimal places.
e) more than 6 smoke? Round this probability to four decimal places.
f) How many of the 21 people would you expect to smoke? Round to four decimal places.
