For each of the following situations, suppose H0: 1 = 2 is being tested against HA: 1

Question:

For each of the following situations, suppose H0: µ1 = µ2 is being tested against HA: µ1 ≠ µ2. State whether or not there is significant evidence for HA.
(a) P-value = 0.085, α = 0.10.
(b) P-value = 0.065, α = 0.05.
(c) ts = 3.75 with 19 degrees of freedom, α = 0.01.
(d) ts = 1.85 with 12 degrees of freedom, α = 0.05.
