To find the 11th percentile, we need to find the value that is greater than 11% of the data. 11% of 100 is 11. So we need to find the value that is greater than 11 values. Counting from the smallest value, we see that the 11th value is 29.8. Therefore, the 11th percentile is 29.8. To find the 11th percentile, we need to find the value that is greater than 11% of the data. 11% of 50 is 5.5, which falls between the 13th and 14th values. The 13th and 14th values are both 29.5, so we take the average of those two values to get 29.8.
