In any distribution how many means are there
WebThe standard normal distribution, z, has a mean of μ = 0 and a standard deviation of σ = 1. Figure 6.3. 1: Standard Normal Curve Luckily, these days technology can find probabilities for you without converting to the zscore and looking the probabilities up in a table. Web-If the original value is not normally distributed, then a sample size of 30 or more is needed to approximate a sample mean distribution to a normal distribution. The larger the sample, the better approximation will be. What generally happens to the sampling error as the sample size is decreased? It gets larger.
