I need help answering questions 2-5.

I need the answer as soon as possible

A school librarian wanted to estimate the proportion of students in the school who had read a certain book. The librarian sampled 50 students from the senior English classes, and 35 of the students in the sample had read the book. Have the conditions for creating a confidence interval for the population proportion been met? A) Yes, because the sample was selected at random. B) Yes, because sampling distributions of proportions are modeled with the normal model. C) Yes, because the sample is large enough to satisfy the normality conditions. D) No, because the sample is not large enough to satisfy the normality conditions.   E) No, because the sample was not selected using a random method.

The question asks for two answers?

Can you make the answer more clearer ?
