Dynamic Random-Access Memory (DRAM) Memory Chips Are Made from Silicon

question 25

Multiple Choice

Dynamic random-access memory (DRAM) memory chips are made from silicon wafers in manufacturing facilities through a very complex process called wafer fabs. The wafers are routed through the fab machines in an order that is referred to as a recipe. The wafers may go through the same machine several times as the chip is created. The data file DRAM Chips contains a sample of processing times, measured in fractions of hours, at a particular machine center for one chip recipe. Compute the median processing time.

• A) 0.31 minutes
• B) 0.24 minutes
• C) 0.21 minutes
• D) 0.44 minutes

Definitions:

Underapplied

A condition where allocated manufacturing overhead for a period is less than the actual overhead incurred, causing unabsorbed overhead costs.

Job-Order Costing System

A cost accounting system that assigns costs to specific batches or job orders, making it easier to track the cost of producing each item or batch.

Overapplied

Occurs when the allocated manufacturing costs exceed the actual manufacturing costs incurred.

Underapplied

Refers to a situation where the allocated or applied costs in an accounting period are less than the actual costs incurred.
