Hy 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: Ha (1) word(s) H: Ha (2) 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 based on the hypothesis test? Since the P-value is (3) - the significance level, (4) the null hypothesis. There (S) 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)<H 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 (6) (7) the null hypothesis. 1: Words Spoken In A Day Male 26,857 17,634 6,197 26.017 27.160 7,983 19,92€ 19.133 25.893 22,252 12,013 10,596 13,686 23.305 Female 19,445 23,048 6,374 17,465 12,473 13,818 12,471 19,005 12.764 19,789 15,763 11,979 16,018 22,741
