if the heights of 99.7% of American men are between 5' and 7' is your estimate of the standard deviation of height of American men? a) 1 inch b) 3 inches c) 4 inches d) 6 inches e) 12 inches I don't understand how to figure this out?

@skinny23 thats a good question lol idk im bored in class and just guessed lol.
can someone who knows this help me please?
I think we will assume it be a normal distribution. Now use the tables to find the Z value and use the formula
so would I do 5-7/ 99.7%?
