Joanne needs to test boxes of pasta to see if they containthe correct amount of product. Each of the 500 boxes ina recent batch has a unique serial number from 1001 to1500 stamped on it. She will pick a random sample of50 boxes by generating a random integer between 1001and 1011 to select the first box, and then selecting everytenth number in sequence. Her method is calledA) cluster sampling.B) convenience sampling.C) multistage sampling.D) stratified sampling.E) systematic sampling.
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.
