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 15,163 26.168 1437 7557 19.264 15,321 14,632 24,909 Female 25,121 13,932 18.187 17.407 13.337 16 792 16.076 18.445 In this example, up 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. 1=(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 the significance level, the null hypothesis . There sufficient evidence to support the claim that males speak fewer 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 of the confidence interval leads to the same conclusion reached in part (a)? The confidence interval is word(s)= uas word(s). (Round to the nearest integer as needed!)
