an
airline carries 200 passengers and has doors with a height of 78in.
heights of men are normally distributed with a mean of 69.0 in and
a standard deviation of 2.8. if a male passenger is randomly
selected find the probability that he can fit through the doorway
without bending
if half of the 200 passengers are men, find the probability
that the mean height of the 100 men is less than 78in

A large study of the heights of 880 adult men found that the
mean height was 70 inches tall. The standard deviation was 4
inches. If the distribution of data was normal, what is the
probability that a randomly selected male from the study was
between 66 and 78 inches tall? Use the 68-95-99.7 rule (sometimes
called the Empirical rule or the Standard Deviation rule). For
example, enter 0.68, NOT 68 or 68%..

Since 911, heightened airline security has increased
frustrations for both airline employees and passengers. Passengers
have to abide by the ever more rules that airline employees must
enforce. For instance, on a flight from Europe to the United
States, a simple passenger request escalated quickly. “John Murphy
asked a flight attendant about a sign telling passengers not to
venture beyond the curtain separating the economy class from the
rest of the plane.”, the New York Times reported. “He wanted to...
