Report the variance of the residuals accurate to 3 decimal places:     s2res=  Report the test statistics for the regression coefficients accurate to 3 decimal places:     t1=      t2=

- October 10, 2022 - Edwin Tunner

This problem is based on problems 18.1, 18.2, 18.9, & 18.10 from Lomax & Hahs-Vaughn, 3rd ed.

I only need the last 3 parts. The s2 res, t1 and t2 please. Thank you!

You are given the following data, where X1 (final percentage in history class) and X2 (number of absences) are used to predict Y (standardized history test score in fifth grade):

Y X1 X2
300 65 7
350 78 3
450 89 1
390 80 1
370 75 4
375 92 6
485 99 0
375 88 3
415 95 2
465 92 2
420 80 2
345 70 3

Determine the following multiple regression values.

Report intercept and slopes for regression equation accurate to 3 decimal places:
    Intercept:  a= 
    Partial slope X1:  b1=
    Partial slope X2:  b2= 

Report sum of squares accurate to 3 decimal places:
    SSreg=
    SSTotal=

Test the significance of the overall regression model (report F-ratio accurate to 3 decimal places and P-value accurate to 4 decimal places):
    F-ratio = 
    P-value = 
These below here is all I need:
Report the variance of the residuals accurate to 3 decimal places:
    s2res= 

Report the test statistics for the regression coefficients accurate to 3 decimal places:
    t1= 
    t2=
