WebIt tells us that the mean in the population is no less than 23. b. There is no way to know without knowing the size of the sample. c. Nothing; it was just a sample. d. We expect that the population mean is equal to 23 because the sample mean is an unbiased estimator of the population mean. d. WebWe have taken a sample of size 50, but that value σ/√n is not the standard deviation of the sample of 50. Rather, it is the SD of the sampling distribution of the sample mean. Imagine taking a sample of size 50, calculate the sample mean, call it xbar1. Then take another sample of size 50, calculate the sample mean, call it xbar2.
