Do you understand what a 95% confidence interval is?

If you did the exercise correctly, you will have correctly captured the answer in your ranges exactly 19 out of 20 times. No more, no less.
That’s kind of dumb, because it’s trivial: just give a range of zero to a googleplex on each one except for one where you put -2 to -1 or something else that is guaranteed to not contain the right answer.
I bet that's why they start with "If you did the exercise correctly..." because the questions are specifically asking for 95% confidence for each of the 20 questions. Your solution only works if you completely ignore that one instruction that appears in each of the 20 questions.
Given that each question individually specifies "95% confidence interval:" in front of each input individually, it suggests that your solution is "kind of dumb" because you are absolutely NOT doing "the exercise correctly..."
Your answer for the question asked in this post is "no" because you clearly do not understand what a 95% confidence interval is." Calling it dumb was not as appropriate as you may have thought before replying. Your solution was not clever, as it was completely incorrect.
