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?

the test statistic is -0.35

the p-value is 0.369

what is the conclusion based on the hypothesis test?
