the following MINITAB output displays presents the results of a hypothesis test for the difference
μ1
- μ2
between two populations means

































two-sample T for X1 vs X2
nmeanSTDevSE mean
A1266.02122.0146.355
B840.64927.3379.665

difference = Mu(X1) - mu(X2)


estimate for difference: 25.372


95% CI for difference: (2.700,48.044)


t- Test of difference = 0 (vs not =) : T-value = 2.193456


                                                              p-value = 0.04706  DF= 13


what is the alternate hypothesis?


A)U1≠U2       B) U1 > U2      C) U1 <>
