Question

Chapter 9, Section 1, Exercise 001 Use the computer output to estimate the intercept beta Subscript 0 and the slope beta Subscript 1. The regression equation is Upper Y ⁢ equals 24.0 plus 4.89 Upper X. Predictor Coef SE Coef T P Constant 24.038 5.192 4.63 0.000 Upper X 4.886 0.7358 6.64 0.000 Intercept beta Subscript 0 Baseline colon Slope beta Subscript 1 Baseline colon

Answer 1

Answer

Using the given computer data output

Intercept

30 24.038

and slope

31 4.886

Rounding to two decimals, we get

Intercept = 24.04 (it is value of dependent variable when independent variable is 0)

and slope = 4.89 (it is showing that for every unit increase in independent variable, there is 4.89 unit increase in dependent variable)
