(A) For the following situation, suppose H0 : μ1 = μ2 is being tested against HA : μ1 > μ2. Find the P-value. State whether or not there is a significant evidence for HA. ts = 1.22 with 4 degrees of freedom, α = 0.05. (B) For the following situation, suppose H0 : μ1 = μ2 is being tested against HA : μ1 = μ2. Find the P-value. State whether or not there is a significant evidence for HA. ts = 1.22 with 4 degrees of freedom, α = 0.05
