QUESTION 1 of 4

Hi Professor Im struggling with a questions that seems pretty simple!

Ch. 10 #3 in the homework. Im doing everything right except for the SST, I'm adding 1368squared/4 + 1279squared/4 + 1471squared/4 + 1454squared/4 = 1946305.5

Then i go on to do the SSE and I subtract 31121.333-1946305 and get -1915183.667

I don't know what I'm doing wrong

QUESTION 3 of 4

Hi professor

in Sect 10.3#25,(what would be the rejection region question), I can get the dftx/df error (4,8) which is the numerator and denominator needed to look up the critical value on the F table but I do not see a given alpha value, you have it listed in the HW answer section but I do not see it listed as a value given and would need that to know for the critical value look up, please help, thank you - Elaine
