According to a recent survey, 92% of high school students plan to attend college. What is the probability that at least 8 out of 10 random high school students plan to attend college? Find the P(at least 8).

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

ksksfksag;

we are given scale of 2 units.

on graph paper the space is 2.5 cm.

length of glass = 8 units.

8 units = 2 units +2 units +2 units +2 units.

each 2 unit is = 2.5cm.

therefore,

8 units = 2 units +2 units +2 units +2 units = 2.5+2.5+2.5+2.5= 10cm.
