A college senior who took the Graduate Record Examination exam scored 560 on the Verbal Reasoning section and 740 on the Quantitative Reasoning section. The mean score for Verbal Reasoning section was 460 with a standard deviation of 132, and the mean score for the Quantitative Reasoning was 452 with a standard deviation of 140. Suppose that both distributions are nearly normal. Round calculated answers to 4 decimal places unless directed otherwise.
(a) Write down the short-hand for these two normal distributions
(b) What is her Z score on the Verbal Reasoning section? On the Quantitative Reasoning section? Draw a standard normal distribution curve and mark these two Z scores.
(c) What do these Z scores tell you?
(d) Relative to others, which section did she do better on?
(e) Find her percentile scores for the two exams.
(f) What percent of the test takers did better than her on the Verbal Reasoning section? On the Quantitative Reasoning section?
Answer:
Kindly check explanation
Step-by-step explanation:
Verbal:
Score, x = 560
Mean, m = 460
Standard deviation, s = 132
Quantitative :
Score, x = 740
Mean, m = 452
Standard deviation, s = 140
a)
Verbal :
X ~ N(460, 132)
Quantitative :
X ~ N(452, 140)
(b)
What is her Z score on the Verbal Reasoning section? On the Quantitative Reasoning section? Draw a standard normal distribution curve and mark these two Z scores.
Zscore = (x - m) / s
Verbal :
Zscore = (560 - 460) / 132 = 0.758
Quantitative :
Zscore = (740 - 452) /140 = 2.057
(c.)
He has a higher standardized score in the quantitative than the verbal score.
(d.)
The Zscore shows that he performed better in the quantitative reasoning than verbal.
(e) Find her percentile scores for the two exams.
(f) What percent of the test takers did better than her on the Verbal Reasoning section? On the Quantitative Reasoning section?
Verbal :
Score greater than 560
P(x > 560) :
Z = (560 - 460) / 132 = 0.758
P(Z > 0.758) = 0.22423 = 22.4%
Quantitative :
Score greater than 740
P(x > 740) :
Z = (740 - 452) / 140 = 2.057
P(Z > 0.758) = 0.0198 = 1.98%

What is the equation of the circle with a radius of 4 and a center at (3, 2) ?
Answer:
(x - 3)^2 + (y + 2)^2 = 16
Step-by-step explanation:
(x - h)^2 + (y - k)^2 = r^2
r = radius
(h, k ) is center of circle.
The center of the circle is (3, 2) and r is 4.
(x - 3)^2 + (y + 2)^2
16
Best of luck :3
Find the radius of a circle if its center is (2,3) and one point on the circle is (5,3).
Answer:
Step-by-step explanation:
radius = distance between (2,3) and (5,3) = √[(5-2)² + (3-3)²] = 3
The required radius of the circle is
center is (2,3)
point on the circle is (5,3).
What is radius?
Radius of the circle is the distance between the center to the circumference.
Radius = [tex]\sqrt{(X_2-X_1)^2+(Y_2-Y_1)^2}[/tex]
=[tex]\sqrt{(5-3)^2-(3-3)^2}[/tex]
Radius = [tex]\sqrt{4}[/tex]
Radius = 2
Thus, the required radius is 2 .
