Question | Hypothesis | Result analysis | Decision |
---|---|---|---|
a) Are the products out of stock resulting backorders? | H0: n = 0; where n = Quantity of product in the stock Ha: n ≥ 1 | p-value < 2.2e−16, for α = 0.05 | Alternative hypothesis is true |
b) Were the most sold items per month producing back-ordered? | H0:\({Backorder}_{Yes}=\mathrm{n}\), n = Average number of products sold per month | p-value < 2.2e−16, for α = 0.05 | The alternative hypothesis is true |
c) Are the lead time factors producing backorders? | H0: \({Backorder}_{Yes}=\)\({factors}_{lead-time}.\) | p-value < 2.2e−16, for α = 0.05 | The alternative hypothesis is true |
d) Are the forecasted demands of products resulting in backorders? | H0: \({Backorder}_{Yes}=\)\({Forecast}_{high}\) | p-value < 2.2e−16, for α = 0.05 | The alternative hypothesis is true |
