question 5. The Boeing 757-200 ER airliner has doors with a height of 70 inches. Heights of women, the continuous random variable X, are normally distributed with a mean of 65 inches and a standard deviation of 6 inches. If 16 female passengers are randomly selected, find the probability that their mean height is above the door height. Hint: the sample size, along the continuous random variable X-bar, is important to consider here.
