Question
Transcribed Image Text:Ho Hd
= O word(s)
H₁ Md <0 word(s)
(Type integers or decimals. Do not round.)
Identify the test statistic.
t = -0.46 (Round to two decimal places as needed.)
Identify the P-value.
P-value = 0.331 (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 - 8714" word(s) <μd < 5328 word(s).
(Round to the nearest integer as needed.)
What feature of the confidence interval leads to the same conclusion reached in part (a)?
Since the confidence interval contains
zero,
fail to reject the null hypothesis.
