H2 Maths 6.3 - Normal Distribution: Finding Probabilities with a GC
What you will learn
- Bag of rice weights X ~ N(5.0, 0.04), so mu = 5.0 and sigma = 0.2.
- P(X < 5.3): Z = (5.3 - 5.0) / 0.2 = 1.5; from GC normalcdf, P(Z < 1.5) = 0.9332.
- P(4.8 < X < 5.2): Z-scores -1 and 1, so P(-1 < Z < 1) = 0.6827.
