Listed below are the numbers of words spoken in a day by each member of eight differant randomly selactad couples. Complete parts (a) and (b) belaw.
Male
15,394 25,400 1424 7724 19.124 16,089 13, 706 24,823 D
Female 24,950 13,913 18.529 18.241 12.726 16,505 16,518 18,624
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, Pg 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 wvords spoken by the male minus words spoken by the female. What are the null and alternative hypotheses for the hypothesis test?
Ho: Ha- 0 word(s)
H, H < 0 word(s)
(Type intagers or decimals. Do not round.)
Identify the test statistic.
t= -0.59 (Round to two dacimal places as needed)
Identify the P-value.
P-value = 0.288 (Round to three decimal places as needed.)
What is the conclusion based on the hypothesis test?
Since the P-value is
greater than
the significance level, fall to reject the nul hypothesis. There is not sufficient evidence to support the claim that males speak fewer words in a day than females.
b. Construct the confidance interval that could be used for the hypothesis test described in part (a). What feature of the confidence interval leads to tha same conclusion reached in part (a)?
The confidance interval is word(s) < Heword(s).
(Round to the nearest integer as needed.)
