Final answer:
The statement is true. When signing the number 68, if you are right-handed, you would twist to the right, and if you are left-handed, you would twist to the left.
Step-by-step explanation:
The statement is true. When signing the number 68, if you are right-handed, you would twist to the right, and if you are left-handed, you would twist to the left. This rule is based on the convention that right-handed people generally twist clockwise and left-handed people twist counterclockwise. The same rule can also be seen in other situations, such as in the direction of current flow and the direction of motion.
