Question 1147829: 6.4 11/An airliner carries 150 passengers and has doors with a height of 78 in. Heights of men are normally distributed with a mean of 69.0 in and a standard deviation of 2.8 in. Complete parts​ (a) through​ (d).
a. If a male passenger is randomly​ selected, find the probability that he can fit through the doorway without bending.
The probability is
nothing.

this is z=(x-mean)/sd
z>(78-69)/2.8, and this is the probability he will have to bend.
z>9/2.8=0.0007
1-0.0007 is 0.9993
