Large Data Sets. Exercises use the same Appendix B data
Chapter 10, Problem 29BSC(choose chapter or problem)
Large Data Sets. Exercises 29–32 use the same Appendix B data sets as Exercises 29–32 in Section 10-2. In each case, find the regression equation, letting the first variable be the predictor (x) variable. Find the indicated predicted values following the prediction procedure summarized in Figure 10-5.
IQ and Brain Volume Refer to Data Set 6 in Appendix B and use the paired data consisting of IQ score and brain volume \((\mathrm{cm} 3)\) . Find the best predicted IQ score for someone with a brain volume of \(1000 \mathrm{~cm} 3\).

The claim is to find the prediction value for someone with a brain volume of 1000 cm3
The regression equation is given by,
= a + bx
Where, a =
b =
