I remember practicing a question about non-parametric tests, and I think the Mann-Whitney is used when the data doesn't meet normality assumptions.

The Mann-Whitney test is definitely used to compare medians, not means. It's a good nonparametric alternative when the assumptions for a t-test aren't met. I feel pretty confident I can answer this one correctly.

I'm pretty lost on this one. I can never remember the difference between the Mann-Whitney test and the t-test. I guess I'll just have to make an educated guess and hope for the best.

Okay, let me think this through. The Mann-Whitney test is a nonparametric test, so it doesn't assume the data follows a normal distribution. It's used to compare the distributions of two independent samples, not just the means. I think the key is remembering it's about medians, not means.
