Assume you have a sample of n1=8, with a sample mean X1= 42 and a sample standard deviation, S1 = 4 and an independent sample of
n2=15 from another population with a sample mean of X2=34 and a sample standard deviation of S2 = 34. The pooled variance, Sp 2 = 776. a. What is the value of the tSTAT for testing H0 : µ1 = µ2?
b. In finding the critical value, how many degrees of freedom are there?
c. What is your statistical decision?
