Math Problem Statement
Samples are drawn from a population with mean 80 and standard deviation 32. Each sample has 369 randomly and independently chosen elements. Use the Central Limit Theorem to estimate the probability that a sample mean is between 79 and 81. Write your answer as a decimal rounded to the nearest thousandth.
