Answer:

[tex]\boxed {\boxed {\sf D. \ 23.5}}[/tex]

Step-by-step explanation:

The median is the number in the middle of a set of data. To find, we place the numbers in order from least to greatest and pick the middle number.

The data set is:

  • 17, 19, 20, 21, 22, 25, 29, 30, 32, 35

This is already in order from least to greatest, so we can begin removing numbers from each side of the list until the middle is reached.

  • 19, 20, 21, 22, 25, 29, 30, 32
  • 20, 21, 22, 25, 29, 30
  • 21, 22, 25, 29
  • 22, 25

Now we have 2 numbers that are in the middle. To find the median, we take the mean or average of these 2 numbers. Add them together, then divide by 2.

  • 22 + 25= 47
  • 47/2 = 23.5

The median of this data set is 23.5 and choice D is correct.
