Listed below are the numbers ot words spoken in a day by each member ot eight different randomly selected couples. Complete parts (a) and (b) below. Male Female 16,108 23,648 25,563 13,668 1437 18,461 7753 17,271 19,056 13,313 15,723 16,425 14,158 16,279 25,475 17,989 a. use a 0.01 significance level to test the claim that among couples, males speak tewer words in a day than females. In this example, Yd is the mean value ot the differences d for the population ot all pairs ot data, where each individual difference d is defined as the words spoken by the male minus words spoken by the temale_ What are the null and alternative hypotheses tortne hypothesis test? C] word(s) HI : word(s) (Type integers or decimals. Do not round.) Identity the test statistic Round to two decimal places as needed.) Identity the P-value. P-value= (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? Since the P-ualue is Y the significance level, Y the null hypothesis. There sufficient evidence to support the claim that males speak tewer words in a day than females. b. Construct the confidence interval that could be used for the hypothesis test described in part (a). What feature ot the confidence interval leads to the same conclusion reached in part (a)? The confidence interval is word(s) < < word(s). (Round to the nearest integer as needed ) What teature of the confidence interval leads to the same conclusion reached in part (a)? Since the confidence interval contains Y the null hypothesis.
