Answer:
Option 2
Step-by-step explanation:
Go through until you find a true statement:
- The number of observations is 10
Count the number of data points. You should end up with 15, so this option is not correct.
-The median of the data set is 10
To find the median, you know that there are a total of 15 data points, so the median would be the mean of the 7th and 8th (because those are the middle numbers). If you look at the data points, the 7th and 8th points are at 10. The mean of 10 and 10 is just 10, so that means the median of the set is 10.
This is the correct answer.
If you want, you can also go through the other options and see that none of them work.
