1. Square root

Hi, I set up the problem but I am not sure how I would solve it.

0.123 ± 1.96 √(0.123)(0.877) / 1000

I suggest using a calculator. How accurate does the answer need to be?

3. I have tried it on the calculator but I was wondering how I would enter it on my calculator. Is there a certain order I need to enter it?

Evaluate the square root. Then use BODMAS.

Order or Indices they're both the same thing.

BEDMAS, BIDMAS, BODMAS, PEDMAS, PIDMAS and PODMAS are all acceptable.

That's if you say Brackets or Parenthesis, and Exponentiation, Indices or Order.
