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. We would like to determine if the LIFO method results in a lower cost of inventory than the FIFO method.If you use the 5% level of significance, what is the critical t value?
