Answer:
The correct option is C.
Explanation:
About 59% of the 45,000 people responded as "Yes" to the question, "Do you regularly read nonfiction novels?”
The sample size is, n = 45,000.
The sample proportion is, p = 0.59.
The sample selected is a voluntary sample, i.e. the individuals provided their responses voluntarily. So, the sample is not a true representative of the population. Though the results tell us little about the population of all adults because of the large sample size.
Thus, the correct option is C.
