Question: For the respondents, fit the linear regression model y = a + bx, where y = price household is willing to pay for cable and x = assessed value of the house. Now, for the nonrespondents, impute the predicted value from this regression model for the missing y values and use the "completed" data set to estimate the average price a household is willing to pay for cable. Compare this estimate to the previous one and to the estimate from the full data set. Is the standard error given by your statistical package correct here? Why, or why not?
