What is the difference between scoring in the 90^t^h percentile on a test and scoring 90% correct on a test? Discuss this question carefully, giving examples to illustrate.

Expert Solution & Answer

To determine

To write: The difference between scoring in the 90^t^h percentile on a test and scoring 90% correct on a test.

Explanation of Solution

Consider an exam of 100 marks and the person scored 90 marks in the exam.

Therefore, the person has 90 percentage.

From the percentage is easy to know that the person is passed or failed.

Now for example:

Consider that 100 people appears for an exam and one person says that his percentile is 90 it means the candidate has done better than the other 89% or 90% of the appeared students in the exam. The rest 8% or 9% of the appeared students in the exam have scored better than the person.

The percentile concept is not easy to know that the person is passed or failed.

Therefore, percentage is different from thepercentile.

Part 1: A linear electrical load draws 1₁ A at a 0.72 lagging power factor. See the table to find ½ for your student ID. When a capacitor is connected, the line current dropped to 122 A and the power factor improved to 0.98 lagging. Supply frequency is 50 Hz. a. Let the current drawn from the source before and after introduction of the capacitor be 1₁ and I₂ respectively. Take the source voltage as the reference and express 11 and 12 as vector quantities in polar form. b. Obtain the capacitor current, Ic = 12 − I₁, graphically as well as using complex number manipulation. Compare the results. c. Express the waveforms of the source current before (į (t)) and after (i2(t)) introduction of the capacitor in the form Im sin(2лft + 0). Hand sketch them on the same graph. Clearly label your plots. d. Analytically solve i̟2(t) − i₁ (t) using the theories of trigonometry to obtain the capacitor current in the form, ic(t) = Icm sin(2πft + 0c). Compare the result with the result in Part b.

What is the difference between scoring in the 90^t^h percentile on a test and scoring 90% correct on a test? Discuss this question carefully, giving examples to illustrate.

Expert Solution & Answer

To determine

To write: The difference between scoring in the 90^t^h percentile on a test and scoring 90% correct on a test.

Explanation of Solution

Consider an exam of 100 marks and the person scored 90 marks in the exam.

Therefore, the person has 90 percentage.

From the percentage is easy to know that the person is passed or failed.

Now for example:

Consider that 100 people appears for an exam and one person says that his percentile is 90 it means the candidate has done better than the other 89% or 90% of the appeared students in the exam. The rest 8% or 9% of the appeared students in the exam have scored better than the person.

The percentile concept is not easy to know that the person is passed or failed.

Therefore, percentage is different from thepercentile.
