Next, let's come up with the sitting distance, which is the length from the front of the seat cushion to the back of the seat in front of it. To design this, we must consider the buttock-to-knee length for men. Men have buttock-to-knee lengths that are normally distributed with a mean of 23.5 inches, and a standard deviation of 1.1 inches. Again, since we cannot accommodate everyone, we must exclude a certain percentage of men with the largest sitting distances. Decide what percentage of men you are willing to exclude. Find the maximum buttock-to-knee length that you are willing to accommodate. Women's buttock-to knee lengths are normally distributed with a mean of 22.7 inches, and a standard deviation of 1 inch. What percentage of women would be able to fit in these seats, based on their buttock-to-knee lengths? You may also choose to add some extra room to the sitting distance for each seat. How much extra room would you add
