Question

Hi my kid is homeschooled and he has this question and I am the worst person at math. please help
Juliet conducted a survey to find the favorite type of book of the students at her school. She asked 20 students from her class what their favorite type of book is. Juliet concludes that short stories is the favorite type of book of the students in her school because 80% of the students in her class like short stories.

Use at least two sentences to explain why Juliet's sample may not be valid. Make sure to use facts to support your answer.

Answer 1

Juliet cannot determine the entire school's book preference just by asking her class. 80% of students may be a high number in her class, but in the end everyone has their own preferences of books.

Answer 2

Answer:

Well, I'm not 100% percent sure but won't she need to ask the whole school instead of her classroom to find out the answer to her problem. Since she wants to know what the WHOLE SCHOOL Prefers her data only has a few people in it.
