Question

Three decimal places on parts that need decimals. The distance of fly balls hit during a baseball season are normally distributed with a mean of 250 ft and a standard deviation of 50ft. Taking samples of size 49 fly balls hit, the sample means are normally distributed with mean 250 and standard deviation 7.14 What is the probability that a sample mean of 49 fly balls is a distance less than 240 ft? -1.40 What is the 80th percentile of sample means in this case? 292.08
