The data are presented in the following table Question list K Age 34 41 49 62 42 28 Rentals 8 8 4 8 10 Answer parts a and b. O Question 12 a) Which of the following is a scatterplot of the data? Question 13 O A. O B. O C. OD Q Question 14 60- 12- 60- N Rentals 2 40- Rentals 6- 2 40- 20- 20- 0 6 12 20 40 60 60 O Question 15 Rentals Age Rentals Age b) Use the scatterplot of the data to check the assumptions and conditions required for inference. O Question 16 Is the linearity condition satisfied? O A. Yes, the plot appears to be straight, so the Linearity Condition is satisfied. O Question 17 O B. Yes, the plot is nonlinear, so the Linearity Condition is satisfied O C. No, the plot is not straight, so the Linearity Condition is not satisfied. D. No, the plot is linear, so the Linearity Condition is not satisfied. O Question 18 O E. The scatterplot of the data cannot be used to determine whether the Linearity Condition is satisfied. A plot of the residuals is also needed to assess the condition. Is the Independence Assumption satisfied? Question 19 O A. No, the sample size is too small for the errors to be independent from one another. O B. Yes, the customers selected cover a wide range of ages, so they are likely to be independent. O Question 20 O C. No, the scatterplot shows a strong correlation in the data, so they are not independent O D. It cannot be determined if the regression errors are independent from the given information. However, it is likely that the customers were selected randomly, which would imply that the errors are probably independent as well.

The data are presented in the following table Question list K Age 34 4 49 62 42 28 Rentals 8 8 4 8 10 Answer parts a and b. O Question 12 ( U. No, the plot is linear, so the Linearity Condition is not satisfied. Question 13 O E. The scatterplot of the data cannot be used to determine whether the Linearity Condition is satisfied. A plot of the residuals is also needed to assess the condition. Is the Independence Assumption satisfied? Question 14 O A. No, the sample size is too small for the errors to be independent from one another. O B. Yes, the customers selected cover a wide range of ages, so they are likely to be independent. Question 15 O C. No, the scatterplot shows a strong correlation in the data, so they are not independent. O D. It cannot be determined if the regression errors are independent from the given information. However, it is likely that the customers were selected randomly, which would imply that the errors are probably independent as well. O E. It cannot be determined whether the Independence Assumption is satisfied from the information given. O Question 16 Is the Equal Spread Condition satisfied? O Question 17 O A. No, the plot is too evenly spread out. O B. No, the plot is more spread out on one side than the other. O C. Yes, the plot appears equally spread throughout. Question 18 O D. It cannot be determined whether the Equal Spread Condition is satisfied from the scatterplot alone. A plot of the residuals against the predicted values is also necessary to test the condition. Is the Normal Population Assumption satisfied? O Question 19 O A. Yes, the data appear to be normally distributed. O B. No, an outlier in the data indicates that the data is not normally distributed. O Question 20 O C. It cannot be determined whether the Normal Population Assumption is met from the scatterplot, but the data set is large enough that it is not important that this condition be satisfied. O D. It cannot be determined whether the Normal Population Assumption is met from the scatterplot alone. A histogram or normal probability plot of the residuals is needed.
