 Question 482894: If, in a sample of n=25 selected from a normal populatin, X=53 and S=10, what are the critical values of t level of significance, a, is 0.01, the null hypothesis, Ho, is u=50, and the alternative hypothesis, H1, is u not equal to 50? Critical value of t are +/-: round four decimal places.Answer by stanbon(57214)   (Show Source): You can put this solution on YOUR website!If, in a sample of n=25 selected from a normal populatin, X=53 and S=10, what are the critical values of t level of significance, a, is 0.01, the null hypothesis, Ho, is u=50, and the alternative hypothesis, H1, is u not equal to 50? ----- The H1 implies this is a 2-tail test. So each tail has 0.005 of the t-values. --------------------------------------------------- InvT(0.005 when df = 24) = 2.7969 Critical value of t are +/-2.7969 -------- Cheers, Stan H.
