Answer:
Option 2) A binomial variable with 25 independent trials
Step-by-step explanation:
We are given the following in the question:
Sample size = n
R: the number of people from the sample who answer yes to the question whether they have read a novel in the past year.
Then, the random variable R follows a binomial distribution:
- There are n independent trials.
- Each trial have two results either they have read the book or they have not read the book
- Probability of success for each trial is same.
Thus, R is a binomial variable with 25 independent trials.
