Hi there, I'm having trouble on this statistics question regarding the minimum table clearance to satisfy the requirement at hand. Any help is appreciated!

A common design requirement is that an environment must t the range of people who fall between the 5'h 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 21.1 in. and a standard deviation of 1.2 in. Females have sitting knee heights that are normally distributed with a mean of 19.2 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 tting 95% of men? l: in. (Round to one decimal place as needed.)
