2. Suppose IQ scores were obtained from randomly selected twins. For 20 such pairs of people, the linear correlation coefficient is 0.849 and the equation of the regression line is ŷ=0.68+0.99x, where x represents the IQ score of the twin born first. Also, the 20 x values have a mean of 100.9 and the 20 y values have a mean of 100.5. What is the best predicted IQ of the twin born second, given that the twin born first has...

The brain volumes (cm cubed) of 20 brains have a mean of 1160.9 cm cubed and a standard deviation of 121.8 cm cubed. Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of 1414.5 cm cubed be significantly high? Significantly low values are _____cm cubedcm3 or lower. (Type an integer or a decimal. Do not round.)
