Hi
Distribution: approximately normal with µ = 170 and σ = 30
Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus
Population:
P(x > 225) = normalcdf(225,9999,170,30) = .0334  0r 3.34%


SAMPLE: n =95
P(x > 225) = normalcdf(225,9999,170,30/√95) = basically zero %  

Wish You the Best in your Studies.µ = 100 and σ = 15
