a).  y=415.113 +(-6.593)x1 +(-4.504)x2

b). s=24.45

c).  y =415.113 +(-6.593)*21.3 +(-4.504)*43 =81.0101

There is convincing evidence at least one of the explanatory variables is significant predictor of the response.

e).  newdata=data.frame(x1=21.3, x2=43)

predict(mod, newdata, interval="confidence")

#prediction interval

predict(mod, newdata, interval="predict")

g).  No, there is not evidence this factor is significant. It should be dropped from the model.
