3b. A linear regression yields R2 = 0. Does this imply that βˆ1 = 0?
Consider a k-variables linear regression model, i.e., Y = X 1β1 + X 2 β2 + ε, Where, X1 is (N . k1 ) , X 2 is (N . k2 ) and k = k1 + k2 . As you may recall, adding columns to the X matrix (including additional regressors in the model) gives a positive definite increase in R2. The adjusted R2 attempts to avoid this phenomenon of ever-increasing R2. Show that the additional k2 number of variables (regressors) in this model increases R2 if the calculated F-statistic in testing the joint statistical significance of coefficients of these additional regressors (β2 ) are larger than one.
Suppose that in a certain chemical process the reaction time y (hr) is related to the temperature (°F) in the chamber in which the reaction takes place according to the simple linear regression model with equation y = 5.10 − 0.01x and ? = 0.07.

In an instrumental variable regression model with one regressor, Xi, andone instrument, Zi, the regression of Xi onto Zi has R2 = 0.1 and n = 50.Is Zi a strong instrument? Would your answer change if R2 = 0.1 and n = 150?
The regression models that we introduced inSections 2 and 6 are linear in the x’s, but, more important,they are also linear in the β’s. Indeed, they can be usedin some problems where the relationship between the x’sand y is not linear. For instance, when the regression isparabolic and of the form μY|x = β0 + β1x + β2x2 we simply use the regression equation μY|x = β0 + β1x1 +β2x2 with x1 = x and x2 = x2. Use this method to fita parabola to the following data on the drying time ofa varnish and the amount of a certain chemical that hasbeen added:Amount of additive Drying time(grams) (hours)x y1 8.52 8.03 6.04 5.05 6.06 5.57 6.5Also, predict the drying time when 6.5 grams of the chem-ical is added.
A “Cobb–Douglas” production function relates production (Q) to factorsof production, capital (K), labor (L), and raw materials (M), and an errorterm u using the equation Q = λKβ1Lβ2Mβ3eu, where λ, β1, β2, and β3 areproduction parameters. Suppose that you have data on production and thefactors of production from a random sample of firms with the same Cobb–Douglas production function. How would you use regression analysis toestimate the production parameters?
