a. Use a 0.01 significance level to test the claim that among couples, males speak fewer words in a day than females.
In this example, " 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?
Ho: Hd = 0 word(s)
H₁: H0 word(s)
(Type integers or decimals. Do not round.)
Identify the test statistic.
C
t= (Round to two decimal places as needed.)
