acted coup parts (a) and (b) below. | Click the icon to view the data on words spoken in a day by the couples. 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, pg 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: He -O word(s) Hạ: H < O 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 =O (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? | the null hypothesis. There 7 the significance level, support the claim that males speak fewer words in a day than females. Since the P-value is sufficient evidence to b. Construct the confidence interval that could be used for the hypothesis test described in part (a). What feature of the confidence interval loads to the same condlusion reached in part (a)? The confidence interval is word(s) < Hg
