A survey asked people "On what percent of days do you get more than 30 minutes of vigorous exercise?" Using their responses we want to estimate the difference in exercise frequency between men and women. We should use a
◦ 1-sample t-interval

◦ 2-sample t-interval
◦ 1-proportion z-interval
◦ 2-proportion z-interval

Assuming neither made a mistake in calculations, which of these possible explanations could account for this apparent discrepancy?

II.  They wrote identical hypotheses, but the one who rejected the null used a higher α-level.
III. They wrote identical hypotheses, but the one who rejected the null used a lower α-level.
