The distribution of actual weights of 8-oz chocolate bars produced by a certain machine is normal with mean 7.7 ounces and standard deviation 0.17 ounces. What is the probability that the average weight of a bar in a Simple Random Sample (SRS) with three of these chocolate bars is between 7.56 and 7.9 ounces? Give your answer to at least 4 decimal places.
