In the article "Attitudes About Marijuana and Political Views" (Psychological Reports, 1973), researchers reported on the use of cannabis by liberals and conservatives during the 1970s.

To test the claim (at 1% significance) that the proportion of voters who smoked cannabis frequently was lower among conservatives, the hypotheses were

H0: P₁ - P₂ = 0 (P₁ = P₂)

Ha:P₁-P₂<0 (P₁<P₂)

Suppose that we conduct a hypothesis test in which a Type II error is very serious. But the Type I error is not very serious.

Which level of significance is the best choice?
