5)The following data represents the course load in credit hours of 32 students: (Show Keystrokes when applicable)
3, 3, 4, 6, 6, 8, 9, 9, 9, 10, 10, 11, 12, 12, 12, 12, 13, 14, 14, 15, 15, 15, 15, 15, 15, 15, 15, 16, 16, 17, 18, 19
- What course load represents the 60th percentile?
- Interpret the meaning of the 60th percentile.
Solutions
Expert Solution
To find the Percentiles we have to first arrange the given observations in Ascending Order.
If you observe the given observations are in Ascending Order. So we no need to make any order.
The Given Observations are:
3,3, 4, 6, 6, 8, 9, 9, 9, 10,10, 11, 12, 12. 12, 12, 13, 14, 14, 15, 15, 15, 15, 15, 15, 15, 15, 16, 16, 17, 18, 19
(a) 60th Percentile
(b)
For Example; If your test score is in the 60th percentile, it means that you scored better than 60 percent of all the test takers. ... If your child's height is in the 60th percentile, it means that 60 percent of the children are shorter than your child, and 40 percent of children are the same or taller than your child.
Therefore 60 Percent of course load is Less that the 14.8 and 40 Percent of course load is greater than the 14.8 in Credit Hours.
