Find the raw scores of the populations Assume you want to perform a z-test to determine whether the means of two populations are equal. To calculate the z-score, find the raw scores for both populations you're evaluating. WebNov 4, 2024 · If alpha = 0.10, then it’s 10% on one side. If it’s two-tailed, then you need to split that 10% into two–5% in both tails. Hence, the 5% in a one-tailed test is the same as a two-tailed test with an alpha of 0.10 because that test has the same 5% on one side (but there’s another 5% in the other tail). It’s similar for CIs. multiple screens settings

It turns out that you can calculate the expected number of runs in a random sequence that has n heads and m tails. The expected number of runs is E (R) = 2 nm / ( n + m) + 1. The three sequences have n =16 heads and m =14 tails, so the expected number of runs is 15.9. how to metal roof a mobile home
