Answer

Brief Explanations:

  1. The sample is from the math - club. Students in the math club are more likely to like math compared to the general student population, so it's a biased sample.
  2. The sample size of 10 students is too small compared to the total of 2500 students in the school, which may not accurately represent the whole student body.

Answer:

Tammy’s sample is not valid because... She only surveyed the top 10 students from the math club, making it not valid because students in the math club are a self - selected group with a higher probability of liking math and the sample size is too small relative to the total student population of 2500.
