This is a problem that I wrote for my statistics class. The objectives for this problem are as follows:
1. Compute percentages.
2. Compute the arithmetic mean.
3. Critically think about whether or not Joe had enough tacos to meet the ‘average’ demand.
What I found was some students had a hard time computing the percentages and some also had a hard time keeping straight how many beef and how many chicken tacos Joe ordered on each day.
