A researcher carried out two studies with prospective parents. The first was to examine whether women feel significantly more tired after the first six months of their pregnancy. For this study, women were asked to complete a questionnaire early in their pregnancy and a second one six months later. 30 women participated in the study. The second study consisted of comparing the stress levels of expectant fathers and expectant mothers. During this study, the 2 members of the couple had to complete a questionnaire separately. 30 couples participated in the study. Do the two studies have the same significance level? Is there one more conservative than the other? Explain your answer.
