Question number-2: Run times at a local marathon are known to follow a left-skewed distribution with a mean of 244 minutes and a standard deviation of 109 minutes. If we select a random sample of 57 people, what is the probability that the average run time of this sample will be between 226.675 minutes and 269.987 minutes?
