In an experiment, college students were given either four quarters or a $1 bill and they could either keep the money or spend it on gum. The results are summarized in the table. Complete parts (a) through (c) below. Purchased Gum Kept the Money Students Given Four Quarters 34 19 Students Given a $1 Bill 12 28 Find the probability of randomly selecting a student who spentthe money, given that the student was given four quarters. The probability is ? (Round to three decimal places as needed.) Find the probability of randomly selecting a student who spentthe money, given that the student was given a $1 bill. The probability is? (Round to three decimal places as needed.) What do the precedingresults suggest? AA student was more likely to have spent the money than to have kept the money. B.A student given four quarters is more likely to have spent the money than a student given a $1 bill. C.A student was more likely to be given four quarters than a $1 bill. D.A student given a $1 bill is more likely to have spent the money than a student given four quarters
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.
