Carla wants to know how many students in her school enjoy watching reality TV shows. She asks all 22 students in her science cla
ss 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? No, it is not a valid inference because she asked all 22 students in her science class instead of taking a sample from her music class 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 Yes, it is a valid inference because she asked all 22 students in her science class Yes, it is a valid inference because her classmates make up a random sample of the students in the school
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. BUT if the class is required, as most science classes are, then it WOULD be a random sample of the school. So the last option would be correct.
My guess though is that the teacher is looking for answer B. </span>
So you wanna take the total of $325 and subtract the original fee of $26 so you have $299. You take the $299 and divide it by 13. That gives you $23, your answer is 23.
