Suppose "true-talent" average exit velocity (AEV) on batted balls for all players is normally distributed with mean 86 mph and a standard deviation of 2 mph. For any sample of individual batted balls hit by one player, the standard deviation of exit velocity around a particular player's true-talent AEV is 8 mph. At this point in the season, Marco Masher has a total of 10 batted balls with an average exit velocity of 94 mph. Given only this information, the best estimate for his true talent exit velocity is closest to which whole number?

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
