Asked by MAX
You want to know the number of students in your school that have a January birthday. You survey the students in your math class. Three students have a January birthday, and 32 do not. So, you conclude that about 8.6% of the students in your school have a January birthday. Determine whether the conclusion is valid. Explain.
my answer: the conclusion is not valid-it's biased because only students in math class were surveyed and that doesn't really serve as a fair representation for the entire school.
