SUMMARY
The discussion focuses on calculating the probability of the difference of means from a single finite population. The participants calculated variances of 78.125 and 50, leading to probabilities of 0.0119 and 0.0024 for exceeding a threshold of 20. They applied the Central Limit Theorem to derive probabilities of 0.1892 and 0.1591 for two different samples. The confusion arises from the interpretation of the population data, emphasizing the need for clarity in statistical concepts.

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
