Answer: -6+13=7
Step-by-step explanation:
Statistic significance requires that your sample be representative of the population, but I'm struggling with this because if the class is an elective then the answer would be: <span>No, it is not a valid inference because she asked all 22 students in her science class instead of taking a sample of the students in her school.

My guess though is that the teacher is looking for answer B.
