significance level to test the claim that among couples, males speak fewer words in a day than females.In this example,
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?
μd
is the H0:
