Split the Bill?A recent study was conducted to compare the cost of restaurant meals when people pay individually versus splitting the bill as a group. In the experiment 48 subjects were randomly assigned to eight groups of six diners each. Half of the people were told they they would each be responsible for individual meals costs and the other half were told to split the cost equally among the six people at the table. The data in SplitBill includes the cost of what each person ordered (in Israeli shekels) and the payment method (Individual or Split). Use StatKey or other technology to construct a randomization distribution using these data to test whether there is sufficient evidence to conclude that the mean cost is lower when diners are paying individually than when they split the bill equally.

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.
