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 15,440 27,145 1430 8012 18, 196 15,675 13,722 25,725 Female 24,267 13, 190 18,446 17,520 13,410 17,290 16,623 18,645 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 wo 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 based on the hypothesis test? the null hypothesis.. There sufficient evidence to support the claim that males speak fewer w Since the P-value is the significance level, than females. usion reached inb. Construct the confidence interval that could be used for the hypothesis test described in part (a). What feature of the The confidence interval is word(s)
