Suppose the systolic blood pressure for healthy children is modeled by p = Bo + B1 In w where is blood pressure in millimeters of mercury and w is weight in pounds. Find the least squares solution to this model using the following data and the associated Normal Equations: W 44 61 81 113 131 In w 3.78 4.11 4.39 4.73 4.88 91 98 103 110 112 Use your results to predict the blood pressure for a 100-pound healthy child. NOTE: Keep all computations accurate (rounded) to the thousandths place until the end... rounding early will cause significantly different results!
