Consider the following regression output where the dependent variable is testscores and the two explanatory variables are the student-teacher ratio and the percent of English learners:
TestScore = 698.9 - 1.10 x STR - 0.650 x PctEL.
You are told that the t-statistic on the student-teacher ratio coefficient is 2.56.
1. The standard error therefore is approximately .
A) 0.43
B) 0.650
C) 0.25
D) 1.96

The correct option is (A).

Step-by-step explanation:

The multiple linear regression equation is given by,  , where α = constant and β = slope coefficients of regression line.

To test if there is a important relationship amid X and Y, we use the t-statistic test.

The t-statistic for regression coefficient analysis is given by,

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

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

The test statistic is found to be, t = 2.56.

The regression coefficient of variable STR is, 1.10.

Compute the standard error of the regression coefficient as follows:

The standard error of the regression coefficient is 0.43.

Thus, the correct option is (A).

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
