The independent variable is ---Select--- x or y and the dependent variable is
---Select--- x or y.

The amount spent on groceries per week (y) and the number of household members (x) are shown below. 3 3 4 15 $385 $420 $464 $545 $206 $620 A USE SALT Determine which variable is the independent variable and which is the dependent variable The independent variable is -Solocd- Vand the dependent variable is -Seloct- V Calculate the correlation coefficient r. (Round your answer to four dedmal places.) r- O Calculate the eguation of the regression line. (Round your numerical values to two decimal places.) Plot the points and the line on a scatterplot. 700 700 600 600 500 500 400 400 300 300 200 1 3 4. 1 200 300 400 300 200 300 400 500 G00 Does the line provide a good description of the data? O Yes, the scatterplot shows a linear pattem, so the line provides a good description of the data O No, the scatterplot showsa nonlinear pattem, so the line does not provide a good desoription of the data.
