Final answer:
The median is the best measure of central tendency in this scenario as it is not affected by extreme values and gives a better sense of the typical amount earned by the student per day.
Step-by-step explanation:
The question asks which measure of central tendency, the mean, median, or mode, best represents the normal amount of money she makes per day. In this scenario, the mean is not a good representation because the outlier of $5,000,000 significantly skews the average.
The mode, which is the most frequent value, may not accurately represent the normal amount as it can be influenced by a few high or low outliers.
Therefore, the median, which is the middle value when the data is arranged in order, is the best measure of central tendency in this case as it is not affected by extreme values and gives a better sense of the typical amount earned by the student per day.
