Ask the Professor Forum

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

Hi Elaine,

If the significance level is not provided, we normally use alpha = 0.05. That is our default significance level.

Hope that helps,

Professor McGuckian
