Webz = x – µ / σ. Where, x is the raw data. µ is the population mean. σ is the standard deviation of the data. When the population mean is known, the score can be calculated by the following formula: z = Ẋ – µ / σ /√n. Where, Ẋ is the population mean of the data points. n is the sample size. Z-Score Table: WebWe want to find P($20,000 X ≤ $30,000). To solve, let Z = (X - $25,000)/$10,000. Note that when x = $20,000, z = ($20,000 - $25,000)/$10,000 = -0.5, and when x = $30,000, z = +0.5. Hence, P($20,000 ≤ X ≤ $30,000) = P(-.5 ≤ Z ≤.5) = 2F(.5) - 1 = 1.383 - 1 = .383. Thus, about 38% of the taxpayers will benefit from the new law. V.

WebA normally distributed random variable with a mean of 0 and a standard deviation of 1 is known as a standard normal random variable. The letter Z will always be used to represent it. Is z-score same as standard deviation? The Z-score shows how far a value deviates from the standard deviation.
