that it not only shows the test statistic value of
65.99 but also a
P
-value of 0.0000 for the test. This
P

the significance level of 0.01. As a matter of fact for such a small
P
-value
one may conclude that the criterion used in purchasing this smart phone is
very much dependent on the gender of the person.
