Question

David's Landscaping has collected data on home values (in thousands of $) and expenditures (in thousands of $) on landscaping with the hope of developing a predictive model to help market to potential new clients. Data for 14 households may be found in the file Landscape. If required, enter negative values as negative numbers. a. Select a scatter diagram with home value as the independent variable. A. B. C. b. What does the scatter plot developed in part (a) indicate about the relationship between the two variables? The scatter diagram indicates a linear relationship between the two variables. c. Use the least squares method to develop the estimated regression equation (to decimals). + d. For every additional 1000 in home value, estimate how much additional will be spent on landscaping (to decimals). $ e. Use the equation estimated in part (c) to predict the landscaping expenditures for a home valued at 575000 (to the nearest whole number). $

Step 1

Without the actual data file, I can't select a scatter diagram. However, you would typically plot home value on the x-axis and landscaping expenditures on the y-axis. b. Again, without the actual scatter plot, I can't definitively say what the relationship is. Show more…

00:01 David's landscaping has collected data on home values in thousands of dollars and expenditures in thousands of money on landscaping with the hope of developing a predictive model to help marketing to potentially, to potential new clients.

00:18 Data for 14 ,000 households can be found in the file.

00:23 So we'll start with a here, develop a scatter diagram with the home value as independent variable.

00:29 So home value is the independent variable.

00:31 So we're going to get rid of this one because it has landscaping and this one because it has landscaping.

00:36 Then we have to take a look and see which scatter plot it is.

00:43 Is it going to be a negative association or a positive association? and so what we can do is we can check at 800.

00:52 It is at 23, approximately 23.

00:57 And at 800 here, it's at about six.

01:01 So if i find 800, it's at 23 .5.

01:04 So you are correct.

01:06 This one is your scatter plot.

01:09 B, what does a scatter plot develop in part a indicate about the relationship between the two variables? so you are right again when you picked.

01:19 The scatter diagram indicates a positive linear relationship between home value and landscaping expenditures.

01:27 As you can see that this definitely does give way to.

01:31 A positive trend in the data...
