Assume that you are testing the difference in the means of two independent populations at the 0.05 level of significance. The null hypothesis is: H0 : µA - µβ ≥ 0 and you have found the test statistic is z=-1.92 What should you conclude?

a) The mean of pop. A is greater than the mean of pop. B because p-value < α.

b) The mean of pop. A is greater than the mean of pop. B because p-value > α.

c) The mean of pop. B is greater than the mean of pop. A because p-value < α.

d) There is no significant difference in the two means because p-value > α.
