Suppose iq scores were obtained for 20 randomly selected sets of twins. the 20 pairs of measurements yield x overbarequals103.26, y overbarequals102.05, requals0.897, p-valueequals0.000, and modifyingabove y with caret equals negative 13.47 plus 1.12 x, where x represents the iq score of the twin born first. find the best predicted value of modifyingabove y with caret given that the twin born first has an iq of 105? use a significance level of 0.05.
