a. since the p-value is small we are confident that the slope is not zero

b. since the p-value is small we are confident that one average is smaller than the other

c. since the p-value is too large the test is inconclusive

d. none of these

3.What is the conclusion?

a. yes, we can confirm the claim

b. No, we cannot confirm the claim
