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 comma 420 26 comma 531 1447 7496 18 comma 687 15 comma 308 14 comma 406 26 comma 052 Female 24 comma 879 13 comma 408 17 comma 700 17 comma 165 13 comma 305 16 comma 733 16 comma 116 18 comma 599 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, mu Subscript d 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? Upper H 0: mu Subscript d ▼ greater than not equals less than equals nothing word(s) Upper H 1: mu Subscript d ▼ not equals less than greater than equals nothing word(s)
