A scientist studying water quality measures the lead level in parts per billion (ppb) at each of 49 randomly chosen locations along a water line. Suppose that the lead levels across all the locations on this line are strongly skewed to the right with a mean of 17 and a standard deviation of 14 Assume that the measurements in the sample are independent. What is the probability that the mean lead level from the sample of 49 measurements x-bar is less than 15
