The monthly salary of all adults in a certain US town is known to be right skewed with a mean of $3700. If a random sample of 40 adults were selected from that town, what would be the shape of the distribution of the sample mean? Why? O Approximately normal by the law of large numbers. O Approximately normal by the central limit theorem. Right skewed because the original distribution is right skewed. We cannot determine the shape of the distribution of the sample mean.
