Answer:
1. 37
2. 25
Step-by-step explanation:
In order to find a percentile of a given number set, you must first put the values in ascending order:
18, 20, 22, 25, 26, 36, 37, 41, 45, 50
70% = 0.7
Since there are 10 numbers in the set, we'll multiply 10 by 0.7
10 × 0.7 = 7
So we are going to look at the seventh number in the set.
18, 20, 22, 25, 26, 36, 37, 41, 45, 50
1 2 3 4 5 6 <em>7</em> 8 9 10
The seventh number in the set is 37.
We're going to do the same for finding the 40th percentile:
40% = 0.4
10 × 0.4 = 4
Finding the fourth number in the set...
18, 20, 22, 25, 26, 36, 37, 41, 45, 50
1 2 3 <em>4</em> 5 6 7 8 9 10
... We get 25
And those are you answers, 37 and 25.
