Ok I solved the first part:

the digits 01 through 42 represent a response of nonfiction.

47 71 18 92 00 20 40 89 02 26 48 33 77 84 74

But can anyone help understand What does p and p̂ mean - in this context??

thanks, so the intervals to answer the question are [-8,-4]    [0,8] ?

Thanks, so the second would be 52 right??

would it be -5?

So C ??
