The cafeteria records that 67% of students buy pizza with a standard deviation of .03 If you took a sample of 100 students and asked who buys pizza, the standard deviation for this group would be ________? For the same sample of 100 students, what is the probability that at least 65% of them bought pizza today.
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.
