Gas Mileage of 2021 Vehicles by Lexus - Fuel Economy Since any linear combination of normal variables is also normal, the sample mean \(\bar X\) is also normally distributed (assuming that each \(X_i\) is normally distributed). We can easily calculate the short-term ROI of a UX research and design project by dividing the new revenue by the cost of the project. In the above example, some studies estimate that approximately 6% of the U.S. population identify as vegan, so rather than assuming 0.5 for p, 0.06 would be used.
