Please I need help with the last part of the question (part b). Thanks

Listed below are the numbers of words spoken in a day by each member of eight different randomly selected couples. Complete parts (a) and (b) below.

Male	15,441	26,995	1394	8019	18,863	15,004	14,034	26,145
Female	24,369	13,310	17,706	18,182	13,422	16,644	16,712	18,036

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,

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?

H0:

d

equals=

word(s)

H1:

d

less than<

(Type integers or decimals. Do not round.)

Identify the test statistic.

t=negative 0.43

(Round to two decimal places as needed.)

Identify the P-value.

P-value=0.339

(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,

fail to reject

the null hypothesis. There

is not

sufficient evidence to support the claim that 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)?

The confidence interval is
