(a) Test whether µ, # H, at the a = 0.05 level of significance for the given sample data.
Determine the null and alternative hypothesis for this test.
O A. Ho:H1 #H2
H1H1 =H2
O B. Ho:H1 = H2
OC. Ho:H1 =H2
O D. Ho:H1 #H2
H1H1 > H2
Transcribed Image Text:Detemine the P-value for this hypothesis test.
Round to three decimal places as needed.)
Should the null hypothesis be rejected?
Do not reject Ho, there is not sufficient evidence to conclude that the two populations have different means.
3. Reject Ho, there is sufficient evidence to conclude that the two populations have different means.
Do not reject Ho, there is sufficient evidence to conclude that the two populations have different means.
D. Reject Ho, there is not sufficient evidence to conclude that the two populations have different means.
(b) Construct a 95% confidence interval about u, - H2:
We are 95% confident that the mean difference is between'
