Using the 420 observations of the California School data set from your textbook,you estimate the following relationship: = 681.44 - 0.61LchPct
n=420,R2=0.75,SER=9.45
where TestScore is the test score and LchPct is the percent of students eligible for subsidized lunch (average = 44.7,max = 100,min = 0).
a.Interpret the regression result.
b.In your interpretation of the slope coefficient in (a)above,does it matter if you start your explanation with "for every x percent increase" rather than "for every x percentage point increase"?
c.The "overall" regression F-statistic is 1149.57.What are the degrees of freedom for this statistic?
d.Find the critical value of the F-statistic at the 1% significance level.Test the null hypothesis that the regression R2= 0.
e.The above equation was estimated using heteroskedasticity robust standard errors.What is the standard error for the slope coefficient?
