Conduct the global F-test of model usefulness at the α=.05 level of significance: Null Hypothesis: Test statistic: F = p-value: Conclusion: Test the hypothesis (at α=.05) that the price-age slope increases as the number of bidders increases. That is, that age and number of bidders interact positively. Null Hypotheses: Test statistic: t =
