Determine the null and alternative hypothesis for this test.
A. Ho:₁ = ₂
H₁ H₁ <H₂
B. Ho:₁ ₂
H₁ H₁ H₂
P =
C. Ho:₁ <H₂
H₁:₁ = H₂
D. Ho:₁ = ₂
H₁ H₁ H₂
Detemine the P-value for this hypothesis test.

A. Reject Ho. There is not sufficient evidence at the α = 0.05 level of significance to conclude that H₁ <H₂.
B. Do not reject Ho. There is sufficient evidence at the x = 0.05 level of significance to conclude that µ₁ <µ₂.
C. Reject Ho. There is sufficient evidence at the α = 0.05 level of significance to conclude that μ₁ <μ₂.
D. Do not reject Ho. There is not sufficient evidence at the x = 0.05 level of significance to conclude that
