the heights of 1000 students in a college are normally distributed with a mean 5’10” and SD 2”. Use 68% for the region from the mean to 1-SD on either side; 94% for the region from the mean to 2-SD on either side and 98% for the region from the mean to 3-SD on either side. Find the approximate number of students in each range of the heights:
28) 5’8”–6’
29) 5’6”–6’2”
30) Above 5’10”
31) Below 6’
32) Above 5’8”
33) 5’8”–6’4”
