The Following Table Shows the Relationship Between the Speed of a Computer's

question 75

Multiple Choice

The following table shows the relationship between the speed of a computer's CPU and the benefits and costs. Assume that all other features of the computer are the same, i.e., CPU speed is the only source of variation. $$\begin{array} { | l | l | l | l | l | } \hline \text { CPU Mhz } & \text { Total Benefit } & \text { Marginal Benefit } & \text { Total Cost } & \text { Marginal Cost } \\\hline 600 & \$ 1,000 & & \$ 900 & \\\hline 700 & \$ 1,500 & & & \$ 100 \\\hline 800 & & \$ 400 & \$ 1,400 & \\\hline 900 & \$ 2,200 & & \$ 1,900 & \\\hline 1,000 & \$ 2,400 & & & \$ 600 \\\hline\end{array}$$ Choosing the 1,000 Mhz computer would be inefficient because:

• A) the marginal benefit is less than the marginal cost.
• B) the marginal benefit is equal to the marginal cost.
• C) it is impossible to tell the difference compared to a 600 Mhz computer.
• D) the marginal benefit is more than the marginal cost.

Retrieval Failure

The inability to recall information from memory, often due to the lack of proper cues or the decay of memory traces.

Encoding Failure

The inability to form new memories because the information was not effectively encoded into long-term memory.

Nonsense Syllables

Strings of letters that do not follow grammatical rules and do not have meaning, used in memory and learning experiments.

Encoding Failure

The inability to recall specific information because of insufficient encoding of the information at the time of memory formation.
