A) Use the regression function p(x) = mx + b with m rounded to the nearest thousandth and b rounded to the nearest whole number.

Compute p(45) rounded to the nearest whole number.

B) Use the regression function p(x)= mx + b with m rounded to the nearest thousandth and b rounded to the nearest whole number.

Find a value of x would make p(x) = 0. Round to the nearest whole number

C) Compute p ( 45 ), rounded to the nearest whole number. Interpret your findings in terms of widget demand and price in complete sentences. Be sure to include the units on 45 and p ( 45 ) in your response.

D) Find a value of x would make p ( x ) = 0. Round to the nearest whole number. Interpret your findings in terms of widget demand and price in complete sentences. Be sure to include the units on x and p ( x ).

E) Look at your plot. Does it look like the price of widgets can reasonably be modeled by a linear function of demand? Explain.
