Question 1179114: IQ (Intelligence Quotient) of students on a campus is normally distributed with μ = 100 and σ^2 = 64. If 100 samples of student IQ data are taken, what is the chance an IQ sample is taken randomly has a value between 110 and 120?

Hi
normally distributed with μ = 100 and σ^2 = 64 0r σ = 8
Using TI or similarly an inexpensive calculator like a Casio fx-115 ES plus

P( 100 < x < 120) = normalcdf(100,120,100,8) = .4938

Wish You the Best in your Studies.
