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.

Short Answer

Expert verified

a). 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.

Step by step solution

01

Part (a) Step 1: Given Information

The table below shows the lot size and assessed value for a sample of residences in a certain location.

02

Part (a) Step 2: Explanation

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.

03

Part (b) Step 1: Given Information

The table below shows the lot size and assessed value for a sample of residences in a certain location.

04

Part (b) Step 2: Explanation

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.

05

Part (c) Step 1: Given Information

The table below shows the lot size and assessed value for a sample of residences in a certain location.

06

Part (c) Step 2: Explanation

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.

4.76 PCBs and Pelicans, Polychlorinated biphenyls (PCBs), industrial pollutants, are known to be carcinogens and a great danger to natural ecosystems. As a result of several studies, PCB production was banned in the United States in 1979and by the Stockholm Convention on Persistent Organic Pollutants in 2001. One study, published in 1972 by R. Risebrough, is titled "Effects of Environmental Pollutants Upon Animals Other Than Man" (Proceedings of the 6th Berkeley Symposium on Mathematics and Statistics, Vl, University of California Press, Pp. 443-463). In that study, 60Anacapa pelican eggs were collected and measured for their shell thickness, in millimeters (mm), and concentration of PCBs, in parts per million (ppm). The data are on the Weiss Stats site.

a. Obtain a scatterplot for the data.

b. Decide whether finding a regression line for the data is reasonable. If so, then also do parts (c)-(f).

13. Identify a use of the coefficient of determination as a descriptive measure.

7. Identify one use of a regression equation.

Age and Price of Orions. In Table 4.2, we provided data on age and price for a sample of 11Orions between 2and 7years old. On the Weiss Stats site, we have given the ages and prices for a sample of 31Orions between 1and 11years old.

a. Obtain a scatterplot for the data.

b. Is it reasonable to find a regression line for the data? Explain your answer.

Fill in the blanks.

a. In the context of regression, an_______ is a data point that lies far from the regression line, relative to the other data points.

b. In regression analysis, an_______ is a data point where removal causes the regression equation to change considerably:
