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.
