Statistics Clarification Question
The problem that was answered by ebaines was very helpful. Could you please clarify the following:
Question: What Verbal Score on the SAT corresponds to the 83rd Percentile Rank if SAT scores are normally distributed?
Answer: 595. To solve we need to find the z score below which .83 of the area under the curve falls and then to use that to solve for the unknown Verbal score on the SAT. From the table, the area under the curve is closest to .82 when z = .95 (z = .96 is also fine to solve this problem).
z = (x )/
.95 = (x 500)/100
95 = (x 500)
x = 595
My Question: Can you please clarify in your answer to how to arrive at .95, when you stated look at the table and see the entry with 0.33 as its entry (actually it's 0.3289, which is closest to 0.33) is z=95. I looked at the table but I am not understanding how you arrived at 0.33 and the number 0.3289. I am trying to learn this so that I can build a strong foundation in stats. Thanks for your help. Evelyn
