To find the first quartile, we need to organize the data in ascending order:

17, 18, 20, 34, 42, 47, 54, 56, 62, 67, 82

Since there are 11 data points, the index of the first quartile (Q1) can be found using the formula:

Index of Q1 = (n+1)/4 = (11+1)/4 = 3

The first quartile is the average of the data points at the index 3 and index 4. In this case, those data points are 20 and 34.

So, the first quartile is (20 + 34)/2 = 54/2 = 27.

Therefore, the first quartile is 27.
