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 15,307 25,731 1373 8028 18,968 15,433 14,017 25,850 Q1 Female 25,178 13,444 18,531 17,349 12,770 16,703 15,743 18,869 3. 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, pd 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? H0: pd word(s) H1: pd word(s) (Type integers or decimals. Do not round.) Identify the test statistic. t= D (Round to two decimal places as needed.) Identify the P-value. Pvalue = D (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? Since the P-value is l sneak fewer words in a dav than females, the signicance level, the null hypothesis. There sufficient evidence to support the claim that males 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 b. Construct the conf d for the hypothesis test described in part (a).
