C3 Refer to Computer Exercise C2 in Chapter 3. Now, use the log of the housing price as the dependent variable: log(price) = o + Bisqrft + B2bdrms + u. (i) You are interested in estimating and obtaining a confidence interval for the percent- age change in price when a 150-square-foot bedroom is added to a house. In decimal form, this is 0, = 150B1 + B2. Use the data in HPRICEL.RAW to estimate 01. (ii) Write B2 in terms of 0, and B1 and plug this into the log(price) equation. (iii) Use part (ii) to obtain a standard error for and use this standard error to construct a 95% confidence interval
