WebbIn a difference in means hypothesis test, we calculate the probability that we would observe the difference in sample means (x̄ 1 - x̄ 2 ), assuming the null hypothesis is true, also known as the p-value. If the p-value is less than the significance level, then we can reject the null hypothesis. Webb8 feb. 2024 · To find the mean (sometimes called the “expected value”) of any probability distribution, we can use the following formula: Mean (Or "Expected Value") of a …

WebbThe mean of a discrete random variable is defined as E ( X) = ∑ x ∈ X x p ( x) In this case X = { 1, 2, 3, 4, 5, 6 }, so that's where you are getting the multiplication. You can think of the probabilities as weighting the importance of each of these 6 numbers.
