1) The Mars company says that before the introduction of purple M&Ms, 20% of the candies were yellow, 20% were red, 10% were orange, 10% were blue, 10% were green, and the rest were brown. You buy a bag of M&Ms and count 29 yellow, 23 red, 12 orange, 14 blue, 8 green and 20 brown. Use a significance level of ? = 0.1. d) Use your calculator to perform the appropriate hypothesis test and report the test statistic, p- value and degrees of freedom. Be sure to write out what you entered in your calculator. e) Write a full conclusion for this test in the context of the problem.
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.
