Use a 0.01 significance level to test the claim that among​ couples, males speak fewer words in a day than females.   In this​ example, μd 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?   H0​: μd equals=   00 ​word(s) H1​: μd less than<   00 ​word(s) ​(Type integers or decimals. Do not​ round.) Identify the test statistic.   t=?? ​(Round to two decimal places as​ needed.)   P=??   b. Construct the confidence interval that could be used for the hypothesis test described in part​ (a).
