How to sketch sampling distribution
WebNov 28, 2015 · A very common thing to do with a probability distribution is to sample from it. In other words, we want to randomly generate numbers (i.e. x values) such that the values of x are in proportion to the PDF. So for the standard normal distribution, N ∼ ( 0, 1) (the red curve in the picture above), most of the values would fall close to somewhere ... 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 {cm} 120cm is one standard deviation below the mean. Shade below that point. Step 3: Add the percentages in the shaded area:
