To investigate how often families eat at home, Harris Interactive surveyed adults living with children under the age of 18. The survey results are shown in the following table. Number of Family Meals per Week Number of Survey Responses 0 5 1 10 2 28 3 35 4 30 5 115 6 118 7 or more 145 For randomly selected family with children under the age of 18, compute the probability the family eats at least four meals at home during the week.
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.
