Reference no: EM132412507

Suppose that the weights of 1-year-old male children are fairly normal with mean 26 pounds, standard deviation 3 pounds. If we randomly sample nine 1-year-old boys, the probability of their sample mean weight being less than 23pounds is 0.0015, and the probability of being greater than 29 pounds is also 0.0015. What is the probability of the sample mean weight being more than 3 pounds away from 26? (Enter your answer to four decimal places.)
