I am confused as to how to find the critical value.
1. determine the F statistic (write the result is X)
2. determine the critical value F, for alpha of .01 (write the result in X.XX)
3. Conclude and discuss the results
Using Gaussian elimination:
Y2-1.96845y1+0-0.015625=0
Y3-1.96845y2+y1-0.015625=0
1.96845y3+y2-0.015625=0
Answer:
Y1 = -0.002584
Y2 = 0.005152
Y3 = 0.002584
