Answer:
29th percentile.
Step-by-step explanation:
Let us arrange our given data from least to greatest order.
2, 4, 4, 4, 4, 4, 5, 6, 6, 6, 8, 8, 9, 12, 13, 13, 13, 13, 13, 15, 25, 35, 40, 62.
To find the percentile value of x we use formula:
![\text{Percentile value of x}=\frac{\text{Number of values less than x}}{\text{Total number of values}}* 100](https://img.qammunity.org/2020/formulas/mathematics/middle-school/96xwxi1mxd4q1vfcuuarp8zh8w3p6wpfku.png)
We can see from our data set that there are 7 numbers less than 6 and total number of data points is 24.
Upon substituting our given values in above formula we will get,
![\text{Percentile value of 6}=(7)/(24)* 100](https://img.qammunity.org/2020/formulas/mathematics/middle-school/fjirkmlce04urgnzoj5ct4p5e4yzw135yx.png)
![\text{Percentile value of 6}=0.291666* 100](https://img.qammunity.org/2020/formulas/mathematics/middle-school/6k3dcupbqxu0gl6r98dmj4mk8ca674lcjx.png)
![\text{Percentile value of 6}=29.1666\approx 29](https://img.qammunity.org/2020/formulas/mathematics/middle-school/yug3k9vgdh8bg73sny0blnwy18xj0gh7b7.png)
Therefore, the percentile of data value 6 is 29th percentile.
