Continuous Probability Distributions
Case Problem: Specialty Toys
1. Information provided by the forecaster
At x = 30,000,
[pic]
[pic]
Normal distribution [pic][pic]
2. @ 15,000
[pic]
P(stockout) = 0.3365 + 0.5000 = 0.8365
@ 18,000
[pic]
P(stockout) = 0.1517 + 0.5000 = 0.6517
@ 24,000[pic]
P(stockout) = 0.5000 - 0.2823 = 0.2177
@ 28,000
[pic]
P(stockout) = 0.5000 - 0.4418 = 0.0582
3. Profit projections for the order quantities under the 3scenarios are computed below:
