State the ordinary least squares (OLS) estimation criterion. State the OLS normal equations. Derive the OLS normal equations from the OLS estimation criterion. Perform a test of the null hypothesis H0:β2 = 0 against the alternative hypothesis H1:β2 ≠ 0 at the 1% significance level ( i.e. for significance level α = 0.01 ). Show how you calculated the test statistic. State the decision rule you use, and the inference you would draw from the test. Briefly explain what...

Propensity Score Matching or Weighted Least Squares A highly paid consulting firm did a study to determine if privately-held financial firms hire fewer women than publicly-held firms. The consulting firm randomly picked 500 privately-held firms and 500 publicly-held firms to interview Among the publicly-held firms, 450 of the 500 firms respond to the survey. The following table gives the results of the study: Publicly-Held Privately-Held Percent of Women in the Firm 20% 25% Number of Firms Responding 400 400 Since...
