Given the following dataset, what is the first quartile? Round to the nearest tenth if necessary.

To find the first quartile (Q1), you need to arrange the values in the dataset in ascending order:
17, 18, 20, 34, 42, 47, 54, 56, 62, 67, 82
Since there are 11 values in the dataset, the first quartile is the value at the 25th percentile, which falls between the 3rd and 4th values.
Q1 = (20 + 34) / 2 = 27
Therefore, the first quartile is 27.

Apologies for the mistake. Let's recalculate the first quartile.
First, you need to arrange the dataset in ascending order:
17, 18, 20, 34, 42, 47, 54, 56, 62, 67, 82
There are 11 values in the dataset. To find the first quartile (Q1), we need to calculate the median of the lower half of the data set. In this case, the lower half is the first 5 values:
Q1 = (20 + 34) / 2 = 27
Therefore, the first quartile is 27.
