I need serious math help and make it snappy please :P?
So I am in AP Statistics and it is torture. I am doing this assignment, it has 7 questions that are all alike, and I have no idea what to do. I am posting the first question so if you could please explain what to do so I can do the rest of them, that would be awesome! Thank you so much.
Glaucoma is a disease of the eye that is manifested by high intraocular pressure. The distribution of intraocular pressure in the general population is approximately normal with mean 16 mm Hg and standard deviation 3.2 mm Hg. If the normal range for intraocular pressure is between 10 and 22 mm Hg, than what proportion of the general population would fall within this range?

P(X < 10.0) = P((x - 16) / 3.2) < (10.0 - 16) / 3.2) = P(Z < -1.88) = 0.0304
P(X < 22.0) = P((x - 16) / 3.2) < (22.0 - 16) / 3.2) = P(Z < 1.88) = 0.9696
P(10.0 < x < 22.0) = 0.9696 - 0.0304 = 0.9392
Sorry if it wasn't snappy enough.
