I just want some clarification on this problem to make sure I understand the answer I got.
Grades from 500 students approximate a normal curve. The mean score was 75 with a standard deviation of 10.
How many students scored less than 60? My answer is 79.35.
Z=65-75/10 = -1
Z= -1 = .1587
x=.1587(500)
x=79.35
Ok so I multiplied the .1587 because that is the area to the left of 60, correct? Then I multiplied that by the 500 to find what 15.87% of 500 is, correct?
