Web'If we have a set of scores that are normally distributed and have a mean of 20 and a standard deviation of 5, what percentage of scores are greater than 20?' Now I know the answer is 50%, because it was a multiple choice question and I guessed, but I've been trying to work it out. WebSep 26, 2024 · Gain: A gain is an increase in the value of an asset or property. A gain arises if the selling or disposition price of the asset is higher than the original purchase or …

WebThe standard deviation σ of X. Solution: Since all probabilities must add up to 1, a = 1 − (0.2 + 0.5 + 0.1) = 0.2. Directly from the table, P(0) = 0.5. From the table, P(X > 0) = P(1) + P(4) = 0.2 + 0.1 = 0.3. From the table, P(X ≥ 0) = P(0) + P(1) + P(4) = 0.5 + 0.2 + 0.1 = 0.8. Web5. P(x = 5) = 1 50. (5)( 1 50) = 5 50. (5 – 2.1) 2 ⋅ 0.02 = 0.1682. Add the values in the third column of the table to find the expected value of X: μ = Expected Value = 105 50 = 2.1. Use μ to complete the table. The fourth column of this table will provide the values you need to calculate the standard deviation. red lobster weeknight specials
