WebAnswer to Solved a sample size on n=2 is used to construct the. Explanation: If the sample size is n = 2, only one possible sample mean can be calculated since there are only two observations in each sample. To create the sampling distribution, multiple samples of size n = 2 must be taken from the population, and the mean of each sample must be calculated.
