Course Hero uses AI to attempt to automatically extract content from documents to surface to you and others so you can study better, e.g., in search results, to enrich docs, and more. Test statistics: t, F, 2, etc. Having said that, here are the "sig fig" rules: When adding or subtracting quantities, the sum/difference should be rounded to the number of decimal places as t. acetic acid 11.87 has 2 digits after the decimal The answer must have 2 digits after the decimal : 12.009 becomes 12.01.
