WebWell, let us recall the formula of how we compute a z-score: \[ Z = \displaystyle \frac{X-\mu}{\sigma}\] Raw Score to X Score Then, based on the definition formula of a z-score, we need to solve for (\(X\)) in order to find the corresponding raw score, and we apply the following formula obtained from solving the equation. We get: WebJul 16, 2024 · 1. If the proportion of people with a given characteristic is p 0, then when you take a sample of size n then (under the right assumptions) the number of people in your sample with the characteristic is a Binomial random variable, i.e. n 0 ∼ B i n ( n, p 0). Under that model, we know that E ( n 0) = n × p 0 and V a r ( n 0) = n p 0 ( 1 − p 0).
