Need Some Help

Forty-two percent of the members in a book club prefer to read nonfiction books. Use the Table of Random Digits below to simulate randomly selecting and asking 15 members, “Do you prefer to read fiction or nonfiction books?”

Let the digits 01 through 42 represent a response of nonfiction.

(1) Start at the beginning of line 122 and write the first 30 digits as two-digit numbers. Circle those that represent a response of nonfiction.

(2) Write p and p̂ for the situation.

What have you done so far?

SO if I start at line 122 and write the first 30 digits as two-digit numbers. I believe I get:
47 71 18 92 00 20 40 89 02 26 48 33 77 84 74.
Now What I do not understand is how to identify those that represent a nonfiction response
and how to write p and p̂ for the situation.

What does p and p̂ mean - in this context? Please define those - mathematically.

As the question said: "Let the digits 01 through to 42 represent a response of nonfiction." Circle them.

P represents the proportion in the population while p̂ represents the proportion in the sample???

'p' represents the proportion in the population while p̂ represents the proportion in the sample???

Is that the definition from your textbook - your class-notes?

Why do you have question marks after the definition? Are you not sure? If you are not sure about the definitions - how are you going to calculate those?

No, I just verified those are in fact the correct definitions. my apologies
