Step-by-step explanation:
6.68% of the students scored at least 19 points on this test while the 85 percentile has a test score of 24.08 points
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
P(x > 19) = P(z > 1.5) = 1 - P(z < 1.5) = 1 - 0.9332 = 0.0668
6.68% of the students scored at least 19 points on this test
b) 85 percentile corresponds to a z score of 1.04
The 85 percentile has a test score of 24.08

275 * .15 = 41.25
275-41.25= 233.75
233.75 * .0725 = 16.95 (I rounded to the nearest thousandths. If you are not rounding, it would be 16.94)
233.75 + 16.95 = 250.70
or
233.75 + 16.94 = 250.69
The ratio is 15:24, which simplifies to 5:8
