Answer:
A) discrete random variable.
Explanation:
Discrete random variables can assume only a finite number of values, and their combined total probabilities must equal 1.
On the other hand, continuous random variables can take any value with an interval or collection of intervals, which means that the possible values are infinite.
A complex random variable is a combination of two real random variables that have rel and imaginary parts.
Answer:
d) relative to others instead of against performance standards.
Explanation:
Contrast error is one that occurs during performance rating where a person is not rated objectively, but against previous people who performed good or badly.
The person's ratings is affected negatively or positively.
A person that performs well subconsciously sets a benchmark in the mind of the rater, and he now rates future participants based on this benchmark and not on performance standards that have been set.
Based on the coordinates of point x and those of point y on the linear production possibilities curve, the opportunity cost of producing one watch is 2 fewer clocks.
<h3>What is the opportunity cost of producing one watch?</h3>
The opportunity cost of producing one watch is the number of clocks that needs to be given up per watch.
This will therefore be the slope of the linear production possibilities curve which can be found as:
= (Y₂ - Y₁) / (X₂ - X₁)
Solving gives:
= (80 - 20) / (20 - 50)
= 60 / -20
= -2 clocks
This means that for every watch produced, there will be 2 clocks that will be foregone to make that watch.
In conclusion, the opportunity cost is 2 clocks.
