A population with a mean of 1,300 and a standard deviation of 400 is known to be highly skewed to the right. If a random sample of 49 items is selected from the population, what is the probability that the sample mean will be less than 1,400? P(?x < 1,400) = (Round to four decimal places as needed.)
