    not entirely sure what to do here, i mean i've gotten the Variance for each, 78.125 & 50, and then... I'm confused because it's coming from one population, not two. hmmf.

    A: .0119 and .0024 respectively, for the prob of being over 20, is this at all right?

    B:So I put them each into the central limit theorem and got: .1892 for the first and .1591 for the second
