Why not?
How to approach this question
Think about the limitations of the data provided. How big is the class? Is one piece of homework enough to judge a general trend? Consider factors that could make this single observation misleading.
Full Answer
The sample size is too small to make a reliable conclusion. / This is just one piece of homework and might not be representative of their usual behaviour.
Even though the calculation supports her statement for this specific piece of homework, we cannot be certain it's a general truth. The conclusion is based on a very small sample (only 29 students in total). A small sample is very susceptible to random variation and may not be representative of a larger population or even the students' long-term behaviour. Furthermore, the data is only for a single piece of homework. The difficulty of the homework, external factors on that particular day, or other variables could have influenced the completion rates. To make a more reliable conclusion, data should be collected over a longer period and for multiple assignments.
Common mistakes
✗ Stating that the calculation was wrong. The question says the data *does* support her view.
✗ Giving a vague answer like "it's not accurate" without explaining why.
