Equation
the Regression Equation $\hat{ Y }$ = 4 + 15x₁ + 2

question 59

Short Answer

Equation
The regression equation, $\hat{ Y }$ = 4 + 1.5x₁ + 2.5x₂ has been fitted to 25 data points.The means of x₁ and x₂ are 30 and 46,respectively.The sum of the squared differences between observed and predicted values of y has been calculated as SSE = 175,and the sum of the squared differences between y values and mean of y is SST = 525.
-Determine the multiple standard error of estimate.
