Final answer:
The median of the list of numbers [3.19], [3.49], [3.79], [3.89], [3.99], [4.19] is 3.89.
Step-by-step explanation:
The median of the list of numbers [3.19], [3.49], [3.79], [3.89], [3.99], [4.19] is 3.89.
To find the median, first sort the numbers in ascending order: [3.19], [3.49], [3.79], [3.89], [3.99], [4.19].
Since the list has an odd number of values, the median is the middle value, which is the fourth value in this case.
