Listed below are the numbers of words spoken in a day by each member of six different couples. The data are randomly selected from the first two columns in Data Set 24
Data Set 24

"Word Counts" in Appendix B.
a. Use a 0.05 significance level to test the claim that among couples, males speak fewer words in a day than females.
b. Construct the confidence interval that could be used for the hypothesis test described in part (a). What feature of the confidence interval leads to the same conclusion reached in part (a)?

Use the indicated Data Sets in Appendix B. The complete data sets can be found at www.TriolaStats.com. Assume that the paired sample data are simple random samples and the differences have a distribution that is approximately normal.
Repeat Exercise 8 "The Spoken Word" using all of the data in the first two columns of Data Set 24 "Word Counts" in Appendix B.
