Question 14

Which statement(s) are correct about the Regression shown here? (Note: There are 2 correct answers).

The dependent variable is the outside temperature

The relationship between outside temperature and number of customers per hour is a Linear Regression

The dashed lines indicate with 95% confidence where all of the process data should fall between

The dashed lines indicate with 95% confidence the estimate for the Quadratic Regression Line

The predicted number of customers per hour is close to 5 if the outside temperature is 10 deg C

Correct Answer: C, D

The graph shows a fitted line plot with a quadratic regression equation, which indicates that the relationship between outside temperature and the number of customers per hour is not linear but quadratic. The dashed lines represent the 95% confidence interval for the regression line, indicating the range within which we are 95% confident that the true regression line lies.
