Assume the true population mean is μ = 80. For a sample of 100 observations the 95% confidence interval around the sample mean has a fixed width of ±1.96 * 20/√100 = ±3.92.

WebThe symbol $\bar{x}$ denotes the sample average. $\bar{x}$ for any particular sample is a number. However, $\bar{x}$ can vary from sample to sample. The distribution of all possible values of $\bar{x}$ for repeated samples of a fixed size from a certain population is called the sampling distribution of $\bar{x}\text{.}$ WebThis is known as stratified random sampling.For taking a sample from a long list a compromise between strict theory and practicalities is known as a systematic random sample.In this case we choose subjects a fixed interval apart on the list, say every tenth subject, but we choose the starting point within the first interval at random. fmg shares
