The flow rate y (m³/min) in a device used for air-quality measurement depends on the pressure drop x (in. of water) across the device's filter. Suppose that for x values between 5 and 20, the two variables are related according to the simple linear regression model with true regression line y = -0.14 + 0.095x. n USE SALT (a) What is the expected change in flow rate associated with a 1 in. increase in pressure drop? |(m³/min) Explain. We expect the change in flow rate (x) to be the y-intercept of the regression line. We expect the change in flow rate (x) to be the slope of the regression line. We expect the change in flow rate (y) to be the slope of the regression line. We expect the change in flow rate (y) to be the y-intercept of the regression line.
