Suppose IQ scores were obtained from randomly selected twins. For 20 such pairs of people, the linear correlation coefficient is 0.910 and the equation of the regression line is y with caret =?5.01+1.05x, where x represents the IQ score of the twin born second. Also, the 20 x values have a mean of 94.76and the 20 y values have a mean of 94.95What is the best predicted IQ of the twin born first, given that the twin born second has an IQ of 98?Critical Values of the Pearson Correlation Coefficient rNOTE: To test H0: rho?equals=0 against H1: rho?not equals?0, reject H0 if the absolute value of r is greater than the critical value in the table.nalpha?equals=0.05alpha?equals=0.0140.9500.99050.8780.95960.8110.91770.7540.87580.7070.83490.6660.798100.6320.765110.6020.735120.5760.708130.5530.684140.5320.661150.5140.641160.4970.623170.4820.606180.4680.590190.4560.575200.4440.561250.3960.505300.3610.463350.3350.430400.3120.402450.2940.378500.2790.361600.2540.330700.2360.305800.2200.286900.2070.2691000.1960.256nalpha?equals=0.05alpha?equals=0.01The best predicted IQ of the twin bornfirst is ____ .
