Question

Suppose an airline decides they are comfortable with excluding the 5% of women with the widest hips. How wide should the airline design the seats using the parameters? Womens hip breadths are normally distributed with a mean of 15.2 inches and a standard deviation of 1.1 inches.

Answer 1

17.009 in

For a normal distribution with mean of 15.2 in and standard deviation of 1.1 inches, we finnd that 5% are excluded when the width of the seats are greater than 17.009 inches.
