Multiple Choice

If we were comparing the difference between the mean number of sports drinks consumed by males versus females,and we calculated a z value of 6.43,we would conclude that:

A) the probability of support of the null hypothesis of no difference is less than .01 because 6.43 is greater than 2.58.
B) the probability of support of the alternative hypothesis of no difference is less than .01 because 6.43 is greater than 2.58.
C) the probability of support of the null hypothesis of no difference is less than .01 because 6.43 is less than 2.58.
D) the probability of support of the alternative hypothesis of no difference is less than .01 because 6.43 is less than 2.58.
E) there is a 6.43 percent chance that the two means are not significantly different.
