Consider the following regression output where the dependent variable is testscores and the two explanatory variables are the st
jeyben [28]

Answer:

The correct option is (A).

Step-by-step explanation:

The multiple linear regression equation is given by,  y=\alpha +\beta _{1} x_{1}+\beta _{2}x_{2}, where <em>α</em> = constant and <em>β</em>_{i} = slope coefficients of regression line.

To test if there is a important relationship amid <em>X</em>_{i} and <em>Y</em>, we use the <em>t</em>-statistic test.

The <em>t</em>-statistic for regression coefficient analysis is given by,

t=\frac{\beta_{i}}{S.E._{\beta_{i}}}

The regression equation for test scores dependent upon the two explanatory variables, the student-teacher ratio and the percent of English learners is:

\text{TestScore} = 698.9 - 1.10 \text{ STR} - 0.650 \text{ PctEL}

A <em>t</em>-test for the significance of the regression coefficient of variable student-teacher ratio (STR) is conducted.

The test statistic is found to be, <em>t</em> = 2.56.

The regression coefficient of variable STR is, 1.10.

Compute the standard error of the regression coefficient as follows:

        t=\frac{\beta_{i}}{S.E._{\beta_{i}}}

S.E._{\beta_{i}}=\frac{\beta_{i}}{t}

          =\frac{1.10}{2.56}\\\\=0.4296875\\\\\approx 0.43

The standard error of the regression coefficient is 0.43.

Thus, the correct option is (A).
