Concept explainers
a)
To identify two variables.
a)
Answer to Problem 41E
Information received or not and the time until he or she saw the 3D image.
Explanation of Solution
Given:
The two variables discussed in this study are information received or not and the time until he or she saw the 3D image.
b)
To specify the variables in quantitative or categorical variables with units.
b)
Answer to Problem 41E
The variables “information receiver or not” is a categorical and “fusion time” is a quantitative.
Explanation of Solution
Given:
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 variables “information receiver or not” is a categorical and “fusion time” is a quantitative.
c)
To compare the distributions.
c)
Explanation of Solution
Given:
The shape of the distributions is left skewed for both. Therefore, the center of the NV group was lower than the center of the VV group. The spread of the NV groups was higher than the spread of the VV group. This experiment shows that the people who received no information needed, in general more time to see the 3D image.
