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)
