A survey found that women's heights are normally distributed with mean 63.1 in. and standard deviation 3.9 in. The survey also found that men's heights are normally distributed with mean 68.4 in. and standard deviation 3.9 in. Consider an executive jet that seats six with a doorway height of 56 in. Complete parts (a) through (c) below. C. The door design is inadequate, because every person needs to be able to get into the aircraft without bending. There is no reason why this should not be implemented. 0)D. The door design is adequate, because although many men will not be able to fit without bending, most women will be able to fit without bending. Thus, a larger door is not needed. c. What doorway height would allow 40% of men to fit without bending? The doorway height that would allow 40% of men to fit without bending is in. (Round to one decimal place as needed.)
