Question
listed below are the numbers of words spoken in a day by each member of eight different randomly selected couples.
male : 15,929 27,076 1,427 7,934 18,681 15,557 13,813 25,628
female: 24,318 13,488 18,878 17,926 13,451 16,866 15,950 18,972
Use a 0.01 significance level to test the claim that among couples, males speak fewer words in a day than females.
Construct the confidence interval that could be used for the hypothesis test described above.
the confidence interval is _________ word(s) <
