Match each description to the correct confidence interval in the diagram below.

Fail to reject H₀ P> 0.05. Not statistically significant despite large sample size, which justifies acceptance of the null hypothesis (CI captures 1 because the RR estimate is close to 1). ___

Fail to reject H₀ P> 0.05. Although the RR estimate is close to 1, we cannot accept the null hypothesis since the CI is wide (imprecise). Cannot distinguish benefit from harm. ___

Reject H₀ and accept H_A.P Not clinically significant. RR estimate is statistically significant but the CI is wide (imprecise). The risk reduction may be large and real, but the upper limit of the CI is too close to 1 to take action. ___

Fail to reject H₀ P> 0.05. Not statistically significant due to small sample size. This signifies a probable type II error (CI captures 1 not because the RR estimate is close to 1 but because the interval is wide). ___

Reject H₀ and accept H_A.P Clinically significant, large sample estimate, upper confidence limit far from null hypothesis RR, a blockbuster drug. ___
