Test the following hypotheses of the difference in population means by using the following data (α = .10) H0: µ1- µ2=0, Ha: µ1- µ2 <0
Sample 1 : X=51.3 σ2=52 n=31; Sample 2: X=53.2 σ2=60 n=32
Use the critical value method to find the critical difference in the mean values required to reject the null hypothesis.
