The heights of three-year-old boys are Normally distributed with a mean of 96 cm. and a standard deviation of 4.5 cm. What is the standard score for a three-year-old boy who is 99.5 cm tall?

one that is bigger than 3 1/2

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
