Document Summary
How to calculate numbers of people rather than percentile? (e. g. mean = 1. 70+- . 10 sec, n = 100) . if there were 100 people in that curve how many will have a score of. 21. 19/100 x 250 = 52. 975 people = 53 people. 28. 81 is the area from the mean and the curve. this is what column 2 says on that the table. that leaves us 21. 19 as the remaining portion. Intelligence scores are arranged so that iq mean = 100 +- 15: what % of population have iq, > 100 b) > 120. The z score is 0 therefore 50% of the curve. Page 1 of 6: if a sample of n = 140, how many will be > 120 iq. We are being asked to find portion c. 120 - 100/15 gives us 20/15 = 1. 33. Answer is 50 - 40. 82 = 9. 18 which is the area remaining for c.
