(a)
To make: a
(a)
Answer to Problem 10E
Explanation of Solution
Given:
Mass: | Rate: |
Calculation:
Here, the explanatory variable is mass and the response variable is metabolic rate.
Thus, mass is used on the horizontal axis and metabolic rate is used on the vertical axis. The graph for scatter plot is shown below.
Conclusion:
Therefore, the scatterplot is drawn.
(b)
To describe:the direction, form, and strength of the relationship.
(b)
Answer to Problem 10E
The graph shows a clear direction:
The form of the relationship is linear.
The relationship is moderately strong
Explanation of Solution
Explantion:
The graph shows a clear direction: the overall pattern moves from lower left to upper right.
That is, states in which women with higher mass tend to have higher metabolic rate. We call this a positive association between the two variables. The form of the relationship is linear. The graph follows a straight line pattern. The relationship is moderately strong because the points don’t deviate greatly from line.
