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 5 2.12 1 .095x. a. what is the expected change in flow rate associated with a 1-in. increase in pressure drop
