Medical stats help needed: If...

Medical stats help needed:

If you have a large number (71) in each group , can you use a parametric test (paired t-test) even if you are unsure of a gaussian distribution? Would you then also be justified in referring to means rather than medians for these data?

If you are looking at how age of subject and another continuous variable influenced a outcome that is a continuous variable, can you simply use separate linear regression analyses for this?
