Hi
Distribution: normal with µ = 32 and σ = 9.5
probability that daily production is:
Continuous Curve:
Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus
P( x < 35.9) = P( x ≤ 35.9) = normalcdf(-9999, 35.9,32,9.5) = .6593
Or
P( x > 58.6) = 1 - P( x ≤ 58.6) = 1 - normalcdf(-9999, 58.6,32,9.5) = 1-.9974 = .0026
Wish You the Best in your Studies.
