Transcribed Image Text:a. Use a 0.05 significance level to test the claim that among couples, males speak fewer words in a day than females.
In this example, H is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the words spoken
by the male minus words spoken by the female. What are the null and alternative hypotheses for the hypothesis test?
Ho: Hd

(Type integers or decimals. Do not round.)
Identify the test statistic.
t= (Round to two decimal places as needed.)
Identify the P-value.
P-value = (Round to three decimal places as needed.)
What is the conclusion based on the hypothesis test?
Since the P-value is
males speak fewer words in a day than females.
the significance level,
the null hypothesis. There
b. Construct the confidence interval that could be used for the hypothesis test described in part (a). What feature of the confidence interval leads to the same
conclusion reached in part (a)?
The confidence interval is word(s)<Hd < word(s).
(Round to one decimal place as needed.)
What feature of the confidence interval leads to the same conclusion reached in part (a)?
Since the confidence interval contains
sufficient evidence to support the claim that
the null hypothesis.
