Make sure to use fax to support your answer.

There are several reasons why Timmy's survey may not be valid. First, the sample size of 25 students is relatively small considering the entire student population of the school. The preferences of a small group of students may not accurately represent the preferences of the entire student body. Additionally, the fact that the survey was only conducted within Tammy's math class may introduce bias into the results. Students in a math class may have a higher likelihood of liking math than students in other classes, so the survey results may not be generalizable to the entire school population. To ensure the validity of the survey results, a larger and more representative sample of students from various classes would need to be surveyed.
