a 2-column table with 5 rows. the first column is labeled year with entries 1, 2, 3, 4, 5. the second column is labeled total (in dollars) with entries 896, 925, 880, 963, 914.
how does the mean of the totals compare to the median?

the median is $1.60 greater than the mean.
the mean is $1.60 greater than the median.
the median is $2.82 greater than the mean.
the mean is $2.82 greater than the median
