atisti Question Help A survey found that women's heights are normally distributed with mean 63.9 in. and standard deviation 2.1 in. The survey also found that men's heights are normally distributed with mean 69.1 in. and standard deviation 3.9 in. Consider an executive jet that seats six with a doorway height of 55.6 in. Complete parts (a) through (c) below. a. What percentage of adult men can fit through the door without bending? %. The percentage of men who can fit without bending is (Round to two decimal places as needed.) b. Does the door design with a height of 55.6 in. appear to be adequate? Why didn't the engineers design a larger door? O A. The door design is adequate, because the majority of people will be able to fit without bending. Thus, a larger door is not needed. O B. 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. OC. The door design is inadequate, but because the jet is relatively small and seats only six people, a much higher door would require major changes in the design and cost of the jet, making a larger height not practical. O 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.

Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
