an environment must fit the range of people who fall between the 5th percentile of women and the 95th percentile for men. In designing an assembly worktable, the sitting knee height must be considered, which is the distance from the bottom of the feet to the top of the knee. Males have sitting knee heights that are normally distributed with a mean of 21.8 inches and a standard Deviation of 1.2 inches. Females have sitting me heights that are normally distributed with a mean of 19.3 inches and a standard deviation of 1.1 inches. What is the minimum table clearance required to satisfy the requirement of fitting 95% of men?
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.
A common design requirement is that an environment must fit the
