P-Value: 0.3312
Since the p-vlaue is greater than the significance level, so we
accept the null hypothesis. There is not sufficient evidence to
support the claim that the males speak fewer words in a day than
females
b) Confidence interval:
The interval contain Zero, so we accept the null hypothesis.
Thus we conclude that the males speak not fewer words in a day than females
