The Mark VI monorail used at Disney World has doors with a
height of 72in. Heights of men are normally distributed with a mean
of 69.5in and a standard deviation of 2.4 in. What percentage of
adult men can fit through the doors without bending?
SOLUTION:
From given data,
The Mark VI monorail used at Disney World has doors with a height of 72 in. Heights of men are normally distributed with a mean of 69.5 in and a standard deviation of 2.4 in.
Mean = = 69.5 in.
Standard deviation = = 2.4 in
X = 72 in.
What percentage of adult men can fit through the doors without bending?
P(X < 72) = P((X-) / < (72-69.5) /2.4)
P(X < 72) = P( Z < 2.5 /2.4)
P(X < 72) = P( Z < 1.04)
P(X < 72) = 0.85083
P(X < 72) = 0.8508
The percentage of adult men can fit through the doors without bending is 85.08%
