Question
Please answer all the parts in the picture below as well as the data table, thank you so much :))
![1. Use a 0.05 significance level to test the claim that among couples, males speak fewer
words in a day than females.
Part A in picture below with data table:
A. What are the null and alternative hypotheses for the hypothesis test
B. Identify the test statistic
C. Identify the p-value
D. What is the conclusion based on the hypothesis test?
Since the P-value is ( ) the significance level, ( ) the null hypothesis. There ( ) sufficient
evidence to support the claim that males speak fewer words in a day than females.
E. 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 ( ) word(s) <ud< word(s)
F. What feature of the confidence interval leads to the same conclusion reached in part A:
Since the confidence interval contains ( ), ( ) the null hypothesis.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F17525826-644e-4b54-80a2-4cc5c7d853ae%2Fc0178e5f-8947-45bb-ad9f-5f875cb54445%2Focbs2sr_processed.jpeg&w=3840&q=75)

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, u. 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?
