A particular article presented data on y = tar content (grains/100 ft³) of a gas stream as a function of x₁ = rotor speed (rev/min) and x₂ = gas
inlet temperature (°F). The following regression model using X₁, X2, X3 = ×₂² and ×4 = X₁X₂ was suggested.
(mean y value) = 86.5 – 0.121x₁ +5.07x2 - 0.0706x3 + 0.001x4
(a) According to this model, what is the mean y value (in grains/100 ft³) if x₁ = 3,400 and x₂ = 55.
grains/100 ft³
(b) For this particular model, does it make sense to interpret the value of ₂ as the average change in tar content associated with a 1-degree
increase in gas inlet temperature when rotor speed is held constant? Explain.
Yes, since there are no other terms involving X2.
O Yes, since there are other terms involving X₂.
● No, since there are other terms involving X2.
O No, since there are no other terms involving X2.
A particular article presented data on y = tar content (grains/100 ft3) of a gas stream as a function of x1 = rotor speed (rev/min) and x2 = gas inlet temperature (°F). The following regression model using x1, x2, x3 = x22 and x4 = x1x2 was suggested.
(mean y value) = 86.5 − 0.124x1 + 5.07x2 − 0.0708x3 + 0.001x4
a.) According to this model, what is the mean y value (in grains/100 ft3) if x1 = 3,200 and x2 = 55.

Further, the regression equation to predict a baby's birth welght based on the mother's age was found to be: Predicted birth weight = -1163.45 + 245.15(age). Based on this information, which one of the following statements is incorrect? O The predicted birth weight for a baby whose mother is 15 years old is 4840.7 grams. O If weight was measured in pounds instead of grams, the value of rwould still be 0.88. O If we switch the variables so that age is the response variable and birth weight is the explanatory variable, r would still be 0,88. O If a mother's age is 25 years, we would not want to use the regression equation to predict the baby's birth weight since this would be considered extrapolation.
