Suppose that 100 random samples are taken from this population and the sample mean is calculated for each sample. If we were to make a histogram of the distribu- tion of the sample means from 100 samples, what kind of shape would we expect the histogram to have if n = 1 for each random sample? That is, what does the sam- pling distribution of the mean look like when the sample size is n = 1?
