Problems 5 and 6. you do not have to compute the slope and y intercept for the least squares line. You can use the SPSS output in each problem. The Linear Regression Equation: The regression equations are listed below if you prefer to compute the coefficients. Y = mx+b m= b =ymx = 5 . The data below are ages and systolic blood pressures (measured in millimeters of mercury) of 9 randomly selected adults. Complete the section below. (Section 9.2) Age, x 38 41 45 48 51 53 Pressure, y 116 120 123 57 131 61 142 65 145 148 150 152 SPSS Output: Model Summary Adjusted R Std.
