The following data are from the test for the flow rate of an engine oil pump as a function of engine rpm: rpm T(C) Q (I/s) 2000 90 0.50 3000 90 0.85 4000 90 1.13 5000 90 1.31 6000 90 1.40 2000 120 0.50 3000 120 0.86 4000 120 1.15 5000 120 1.35 6000 120 1.46 (a) Plot these data as two curves, one for each of the two temperatures. (b) Find a suitable multiple regression model Q = !(rpm, T). Consider terms of rpm, T, rpm2, and rpm X T. (c) Using the regression formula, compute values of
