Question

A 90% confidence interval for p1 - p2 is (0.03, 0.14). What conclusion can be drawn about the claim that p1 = p2?

Accepted Answer

Since zero is not in the interval, we reject the claim that p1 = p2.

Answer

The interval is not relevant to the claim.

Answer

We must conduct a hypothesis test to decide.

Answer

Since zero is in the interval, we fail to reject the claim.
