Suppose iq scores were obtained for 20 randomly selected sets of twins. the 20 pairs of measurements yield x overbarequals99.23, y overbarequals98.1, requals0.917, p-valueequals0.000, and modifyingabove y with caret equals negative 1.76 plus 1.01 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 103? use a significance level of 0.05.
