To compare two kinds of front-end designs, six of eachkind were installed on a certain make of compact car.Then each car was run into a concrete wall at 5 milesper hour, and the following are the costs of the repairs(in dollars):Design 1: 127 168 143 165 122 139Design 2: 154 135 132 171 153 149Use the four steps in the initial part of Section 1 to testat the 0.01 level of significance whether the differencebetween the means of these two samples is significant.
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.
To compare two kinds of front-end designs, six of each
kind were installed on a certain make of compact car.
Then each car was run into a concrete wall at 5 miles
per hour, and the following are the costs of the repairs
(in dollars):
Design 1: 127 168 143 165 122 139
Design 2: 154 135 132 171 153 149
Use the four steps in the initial part of Section 1 to test
at the 0.01 level of significance whether the difference
between the means of these two samples is significant.
