Question

What is the standard deviation of adult human heights for males and females?

Answer 1

Obviously the size of the standard deviation would vary across countries and by other factors. That said, I think good data on a few representative countries would be sufficient to get a reasonable sense of what it typically is and the extent to which the standard deviation varies
It's probably around 7 cm for men and 6 cm for women

Answer 2

For example, adult male heights are on average 70 inches  (5'10) with a standard deviation of 4 inches. Adult women are on average a bit shorter and less variable in height with a mean height of 65  inches (5'5) and standard deviation of 3.5 inches. 
for uh Ajay there's a formula to make it answer easier‼️‼️‼️‼️‼️




μ is the mean,σ is the standard deviation of the population, π is approximately 3.1415 and e is approximately 2.17. The x would be a single value in the graph. For example, for an adult male of 72 inches is an x. Plugging in the values gets you a value of .088016, which is just one small sliver of the bell curve on the right side just past the center.  If you did this for say 100 or so heights then you'd get something that looked like a bell-curve. The density function is rarely used. What's really used a lot is the cumulative probability function which will be explored in future lessons.
hope you're satisfied ❤️❤️❤️❤️
