(a) Test whether u, # µ, 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
H1:H1 =H2
VB. Ho:H1 =H2
H1:H1 # H2
O C. Ho:H1 # H2
H1:H1> H2
O D. Ho:H1 = H2
H1:H1 > H2
Detemine the P-value for this hypothesis test.
P= 0.102 (Round to three decimal places as needed.)
Should the null hypothesis be rejected?
O A. Do not reject Ho, there is not sufficient evidence to conclude that the two populations have different means.
O B. Do not reject Ho, there is sufficient evidence to conclude that the two populations have different means.
O C. Reject Ho, there is sufficient evidence to conclude that the two populations have different means.
O D. Reject Ho, there is not sufficient evidence to conclude that the two populations have different means.
