(d) For each sample, calculate abs(b1i − mean(b1)), where mean(b1) indicates the mean of the bis. Plot these values against SEb1i and obtain the correlation coefficient (r)

between these two variables. Obtain the one-sided p-value for the null hypothesis

????=0, with the alternative hypothesis ????>0, where ???? is the true correlation coefficient of which r is an estimate. Comment on these results.
