To explain why it would not be appropriate to perform a chi-square test for goodness of fit using these data.
Answer to Problem 7E
Given variable is quantitative so it is not appropriate to perform a chi-square test for goodness of fit.
Explanation of Solution
Given:
Night | Sunday | Monday | Tuesday | Wednesday | Thursday | Friday | Saturday |
Average time | 130 | 108 | 115 | 104 | 99 | 37 | 62 |
Categorical variable: It describes the quality or characteristics of the data. It does not have numeric or quantitative meaning.
Quantitative variable: The variable expressed numerically and it has numeric meaning.
The variable “average time” is quantitative variables. We know, chi-square test is used for categorical variable. Hence, it would not appropriate to perform a chi-square test for goodness of fit.
