The mean number of food items donated is greater

Answer 1

To determine which statement must be true about the mean, median, and mode of the data, we need to analyze the bar graph provided.

We see that the data is not normally distributed, but rather skewed to the right. Therefore, the mean will be greater than the median, as the mean is affected by outliers and extreme values, which in this case will pull it towards the higher end.

Furthermore, since there is no single value that appears more frequently than any other, there is no mode for this data set.

Therefore, the statement that must be true is:

The mean number of food items donated is greater than the median number of food items donated. (Option K)
