Suppose we are told that the SAT Critical Reading test is normally distributed with a mean of 496 and a standard deviation of 75. What is the probability that a randomly
selected student who took the SAT has a critical reading score higher than 630?

step-by-step explanation:

5

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
