Answer:
A) Electroencephalograph
Explanation:
Electroencephalography functions by capturing the brain's electrical activities. Therefore, for an analysis of REM versus slow wave sleep, the electroencephalograph is the suitable method. It documents the brain's electrical activity over time, allowing for monitoring and diagnosing sleeping disorders, states of anesthesia, comas, brain death, and other conditions, including epilepsy.
Response:
C. a 5% reduction in price results in a 7.5% rise in quantity demanded
Clarification:
To arrive at this conclusion, we utilize the price elasticity of demand equation
Price elasticity = %change in quantity demanded/% change in price
Next, we substitute the relevant values into the equation
1.5 = 7.5% / 5%
This confirms that the proper answer is C as dividing 7.5 by 5 yields a value of 1.5.
An elasticity value of 1.5 indicates that the product is fairly elastic: implying the quantity demanded will adjust more significantly than the price. This is evident in the current scenario: quantity demanded increased by 7.5%, while the price only decreased by 5%.
