The amount of time it takes a five year-old eat a PB&J sandwich is uniformly distributed with a mean of 15 minutes and a standard deviation of 4 minutes. If samples of 36 five year-olds are randomly selected, what is the mean of all sample means for number of minutes it takes a five year-old to eat a PB&J sandwich?
