Question

A statistics student is taking a poll of his high school classmates and their senior prom preferences. He asked those who polled, “last year tickets for the senior prom were $60 each. This year tickets will need to be 70$ if we have a live band preform. Would you like to see a live band preform at this years senior prom?” Is this a valid question?

A. No, because A random sample of all seniors in the country should have been taken to determine if a live band should perform at the high school senior prom.

B. No, Because informing the students that there will be a $10 increase in the cost of a prom ticket may make them more likely to see that they would not like a live band performance

C. No because students should be giving a sample of the bands music to allow them to offer a more informed opinion

D. No because questions about musical preferences are always invalid because you cannot measure peoples opinions on subjective matters like music and other creative arts

Answer 1

I would say choice B. Students can't afford senior prom tickets when prices increase. If the statistics student wants to have a live band performance at a senior prom, the price of tickets must increase in order to cover the cost. Most likely students would prefer to go to their senior prom without a live band performance.
