Answer:
The selections are dependent.
Yes, they can be treated as independent (less than 5% of the population).
Step-by-step explanation:
Since the selections are made without replacement, each selection affects the outcome of the next selection and, therefore, the selections are dependent.
Although they are dependent, the selections can be treated as independent if the sample size is no more than 5% of the total population. In this case, the sample size is 1235 adults out of a population of 15,958,866 adults. The percentage represented by the sample is:
Thus the selections can be treated as independent for the purposes of calculations.
I know this is probably too late but its 60%

Ratio of girls to boys is (1/3*X) / (2/3*X).
That is, 1:2
Similarly, ratio of boys to girls is (2/3*X) / (1/3*X).
That is, 2:1
Step-by-step explanation:
- Assume, total Number of students in the class is X. Since, 1/3 part of the class is girls, this makes 2/3 part of the class boys.
- Total number of girls will be equal to 1/3 *X. Total number of boys is equal to 2/3*X.
- So, ratio of girls to boys is (1/3*X) / (2/3*X).
That is, 1:2. Similarly, ratio of boys to girls is (2/3*X) / (1/3*X). That is, 2:1
