Presentation for normal distribution help please

I have a problem that i am trying to sketch the curve. the problem is

1. SAT (combined) scores of college seniors in high school has the normal distribution with mean 1050 and standard deviation 150.What is the relative frequency college seniors who have SAT score X less than 756?

I get the z score and get 756-1050 divide by 150 = -1.96 and converts to .0250.

now to sketch this how would i do it i looked at a site but im not sure if

its right or what i put for above, below, or between.

any help would be great since i have a presentation tomorrow

I believe you want to put:
choose the" below"
enter " -1.96"

the curve will show in blue the area below -1.96 with a answer .024998
