Part a. What are the null and alternative hypothesis? What is the test statistic? What is the p-value? What is the conclusion based on the hypothesis test? Part b Construct the confidence interval that would 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).

Listed below are the numbers of words spoken in a day by each member of eight different randomly selected couples. Complete parts (a) and (b) below. Male 15,071 25,540 1442 7668 18,895 15,796 13,913 25,133 Female 24,291 13,827 18,894 17,235 12,616 17,433 16,646 18,504 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, Ho 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 word(s) H1: Hd word(s) (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 hased on the hunnthesis test?
