- You'd like to test the null hypothesis that the means of the two samples (column A and column B) are the same. The alternative hypothesis is that they are not the same. You have no reason to believe that the standard deviations of the two samples are equal. Test at the alpha = 0.10 level. After using Excel, what do you conclude? Are the means the same?Where are the critical region(s) located in a z-distribution if a two-tailed hypothesis test was conducted using an alpha = 0.0892?
