You have estimated the relationship between test scores and the student-teacher ratiounder the assumption of homoskedasticity of the error terms. the regression output is asfollows: ^testscore = 698.9 - 2.28x str, and the standard error on the slope is 0.48. thehomoskedasticity-only “overall” regression f- statistic for the hypothesis that theregression r2 is zero is approximatelya. 0.96b. 1.96c. 22.56d. 4.75

The correct option is c.

Step-by-step explanation:

The given regression output is

        ... (1)

The standard error on the slope is 0.48.

The slope intercept form of regression line  is

              .... (2)

The test statistic is a t statistic (t) defined by the following equation.

      ... (3)

From (1) and (2) we get

Substitute and SE=0.48 in equation (3).

So, the F-statistics is

Therefore the correct option is c.
