Heads: 7

Tails : 3

and using the same logic you used we would have 2 proportions here as well. But really the sample size is fixed so if you know one of the numbers then you know the other. There is really only one proportion that matters here.

Another way to think about it: If the problem instead said that they took a random sample of 100 students and the result was that 58 said to extend the school year into summer. Would this sound like just one-proportion now? You could figure out the # of students (and thus the proportion) that disagree with that statement but it's still just a "one-proportion" problem right?

The answer key is C, I choose D, still do not understand why the answer is C. Thank you.

However (C) is probably the "most" wrong because the "actual" distance isn't a variable here. The actual distance is a parameter that we want to estimate and that distance isn't changing. There is a "true" distance and we are just trying to estimate it.
