Listed below are the numbers of words spoken in a day by each member of eight different randomly selected couples. Complete part
s (a) and (b) below.
Male Female
16,051 24,017
26,378 12,962
1440 17,644
7875 17,399
18,237 12,486
15,728 16,581
14,306 16,533
26,823 18,967
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?
