Answer 2

Old question, answering to close

This data set has an outlier (200). You can confirm this by calculating Q3 + (1.5*IQR), to confirm that 200 is above the result. Because we have an outlier, the median is the best measure of central tendency.

For the second part of the problem: average = (sum of data points) / (number of data points)

In this case, your new average is 250, your number of data points is 10, and your sum is the sum of the first 9 data points + the unknown x. solve for x.
