Text Contents ideo and Resource Type here to search Homework The best predicted value of y is. (Round to two decimal places as needed.) Tutoring Help me solve this Suppose IQ scores were obtained for 20 randomly selected sets of twins. The 20 pairs of measurements yield x=97.78, y=99.25, r=0.897, P-value=0.000, and y = -0.88 +1.02x, where x represents the IQ score of the twin born first. Find the best predicted value of y given that the twin born first has an IQ of 103? Use a significance level of 0.05.
