WebNormal distribution curve – Example 1 The following is a normal distribution for a continuous random variable with mean = 3 and standard deviation = 1. We note that: The normal curve is bell-shaped and symmetric around its mean or 3. The highest density (peak) is at the mean of 3, and as we move away from 3, the density fades away. WebStep 1: Sketch a normal distribution with a mean of \mu=150\,\text {cm} μ = 150cm and a standard deviation of \sigma=30\,\text {cm} σ = 30cm. Step 2: The diameter of 120\,\text …
