LAK15TTHEShaped more like a normal distribution.ⒸShaped like neither the population or the normal distribution.Shaped more like the population. A hypothetical distribution for a population of test scores is displayedbelow. The population has a mean of 60.4, a median of 62.8, and astandard deviation of 6.404. Each of the other four graphs labeled A toD represents possible distributions of sample means for randomsamples drawn from the population.What do you expect for the shape of the sampling distribution (thedistribution of sample means for all possible samples of size n = 100)?POULATOASDZI
