The heights of 1000 students in a college are normally distributed with a mean 5’10” and SD 2”. Find the approximate number of students in each range of the heights:

Question

1) 5’8”-6’
2) 5’6”-6’2”
3) Above 5’10”
4) Below 6’
5) Above 5’8”
6) 5’8”-6’4”
*Use 68% for 1 SD, 94% for 2 SD and 98% for 3 SD. (Hint: draw a normal curve, divide the curve into 1, 2 and 3 SD and then put 1%, 2%, 13%, 34%, 34%, 13%, 2%, and 1% in each section from left to right.)
