Hi
Distribution: normal with µ = 53.6 and σ = 2.8
Chose 1
Continuous Curve
Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus

P( x < 49) =  P( x ≤ 49) = normalcdf(-9999,49,53.6,2.8) = .0502
P( x > 48.8) = normalcdf(48.8, 9999,53.6,2.8) = .9568
Wish You the Best in your Studies.
