Question

(08.01) Carla wants to know how many students in her school enjoy watching reality TV shows. She asks all 22 students in her science class and finds that 40% of her classmates enjoy watching reality TV shows. She claims that 40% of the school's student population would be expected to enjoy watching reality TV shows. Is Carla making a valid inference about her population?

Answer 1

She is not making a valid inference because she only asked 22 students out of the entire school's population.

Answer 2

Answer:

No, Carla is not making a valid inference.

Step-by-step explanation:

First of all, the sample population is only 22, in the whole school which might have a population of 1000 or more students. This is very small sample to derive any valid inference. Secondly, she asked the question to only her class and 40% students of her class only like reality shows. This is not necessary that each class has 40% students who like the same. It might be possible that many students don't like such shows.

So, this cannot be a valid inference.
