Part 1
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,
μd
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?
H0:
μd
equals=
00 word(s)
H1:
μd
less than<
00 word(s)
(Type integers or decimals. Do not round.)
Part 2

t=negative 1.73−1.73
(Round to two decimal places as needed.)
Part 3
Identify the P-value.
