(a) fit a model with total sat score as the response and expend and takers as predictors. test the hypothesis that βexpend = βtakers = 0. do any of the two predictors have an effect on the response? (b) now add ratio to the model. test the hypothesis that βratio = 0. compare this model to the previous one using an f-test. demonstrate that the f-test and t-test here are equivalent.

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
