Q.4.157
Question
Acreage and Value. The data from Exercise 4.73 for lot size (in acres) and assessed value (in thousands of dollars) for a sample of homes in a particular area are on the WeissStats site.
Step-by-Step Solution
Verifieda). The linear correlation coefficient was chosen because it provides a descriptive measure of data.
b). The linear correlation coefficient is left out of the equation.
c). There is no calculation of the linear correlation coefficient.
The table below shows the lot size and assessed value for a sample of residences in a certain location.
Draw a scatter plot showing the relationship between lot size and assessed value for a sample of properties in a certain location.
The scatter plot shows that the data points are distributed non-linearly.
As a result, the linear correlation coefficient, which is not a descriptive data metric, is used. As a result, parts b and c have been left out.
The table below shows the lot size and assessed value for a sample of residences in a certain location.
Component a provides the scatter plot for lot size and assessed value for a sample of dwellings in a certain location.
The scatter plot shows that the data points are distributed nonlinearly.
As a result, the linear correlation coefficient, which is not a descriptive data metric, is used.
As a result, the linear correlation coefficient is omitted from the equation.
The table below shows the lot size and assessed value for a sample of residences in a certain location.
Using the data from section a, we must build a scatter plot for lot size and assessed value for a sample of dwellings in a specific region.
After looking at the scatter plot, we decided to use the linear correlation coefficient. A descriptive measure of data is not the linear correlation coefficient.
As a result, there is no calculation of the linear correlation coefficient.
