WebJul 1, 2024 · The normal distribution, which is continuous, is the most important of all the probability distributions. Its graph is bell-shaped. This bell-shaped curve is used in almost all disciplines. Since it is a continuous distribution, the total area under the curve is one. The parameters of the normal are the mean \(\mu\) and the standard deviation σ. Webeach of the following: 1. z=0.96 2. z=1.74 3. z=2.18 4. z=2.69 5. z=3.00 Summary Properties of the Normal Probability Distribution The distribution curve is bell-shaped. The curve is symmetrical about its center. The mean, the median, and the mode coincide at the center. The width of the curve is determined by the standard deviation of the ...
WebA standard normal distribution has a mean of 0 and variance of 1. This is also known as a z distribution. You may see the notation N ( μ, σ 2) where N signifies that the distribution is normal, μ is the mean, and σ 2 is the variance. A Z distribution may be described as N ( 0, 1).
