To find the first quartile, we need to arrange the dataset in ascending order:

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

The dataset has 11 numbers, so the first quartile would be the median of the lower half of the numbers. Since 11 is an odd number, the median of the lower half would be the average of the middle two numbers, which are 18 and 20.

First quartile = (18 + 20) / 2 = 19

Therefore, the first quartile of the dataset is 19.
