A hypothetical distribution for a population of test scores is displayed below. The population has a mean of 60.4, a median of 62.8, and a standard deviation of 6.404. Each of the other four graphs labeled A to D represents possible distributions of sample means for random samples drawn from the population. What do you expect for the shape of the sampling distribution (the distribution of sample means for all possible samples of size n = 100)? POPULATION FELAN
