Accounting procedures allow a business to evaluate its inventory
costs based on
two methods: LIFO (Last In First Out) or FIFO (First In First Out).
A manufacturer evaluated
its finished goods inventory (in thousands) for five products with
the LIFO and FIFO methods.
To analyze the difference, they computed (FIFO - LIFO) for each
product. Based on the
following results, does the LIFO method result in a lower cost of
inventory than the FIFO
method?
Product | FIFO | LIFO |
---|---|---|
1 | 225 | 221 |
2 | 119 | 100 |
3 | 100 | 113 |
4 | 212 | 200 |
5 | 248 | 245 |
What is the decision at the 5% level of significance?
