I need answers for A, B, C

The flow rate in a device used for air quality measurement depends on the pressure dropx (inches of water) across the device's filter. Suppose that forx values between 5 and 20, these two variables are related according to the simple linear regression model with true regression liney = -0.14 + 0.091x.

(a) What is the true average flow rate for a pressure drop of 10 in.? and A drop of 15 in.?

(b) What is the true average change in flow rate associated with a 1-inch increase in pressure drop?

(c) What is the average change in flow rate when pressure drop decreases by 5 in.?
