A common design requirement is that an environment must fit the range of people who fall between the 5th percentile
for women and the 95th
percentile for men. In designing an assembly work table, 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 21.9 in, and a standard deviation of 1.2 in, Females have sitting knee heights that are normally distributed with a mean of 19.5 in. and a standard deviation of 1.1 in. Use this information to
answer the following questions
What is the minimum table clearance required to satisfy the requirement of fitting 95% of men?
