Question
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 $000s) 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?
This example is what type of test?
Multiple Choice
A test of proportions
A two-sample test of means
A paired t-test
A one-sample test of means
Product FIFO (F) LIFO (L) 1 225 221 2 119 100 3 100 113 4 212 200 5 248 245Explanation / Answer
Both the observations FIFO & LIFO both are taken on the same product
It means sample FIFO & LIFO are not independent,they are correlated or paired
so this example is of paired t-test
Answer is " A paired t-test"
