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 15,674 27,343 1382 8036 18,811 16,060 14,416 25,465 Female 25, 180 13,254 18,752 18,284 12,492 16,662 16,715 19,401 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, uo 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.
