The National Sleep Foundation reported that 36.8% of all adults snore. Of the people who snore 87% are over the age of 30. 81.5% of people in their study were over the age of 30. a. write the above statements in probability notation. b. Find the probability that someone is over 30 and snores. c. Find the probability that someone is over or snores. d. Given someone is over 30, what is the probability that he or she snores. e. What is the probability that someone does not snore? f. Are snoring and being over 30 mutually exclusive events? Explain with probabilities. g. Are snoring and being over 30 independent events? Explain with probabilities.
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.
