Simple average question using sig figs within ± 0.0 ? 1. The problem statement, all variables and given/known data Consider the following measurements of mileages: 23.8 mph, 20.1 mph, 26.5 mph, 20.7 mph, 21.7 mph, 27.6 mph, 30 mph, 28 mph, 27.4 mph, 34.3 mph, 26.5 mph, 32.7 mph. What is the average mileage (using sig figs)? Answer in units of mph Your answer must be within ± 0.0 mph. 2. Relevant equations Avg=Total Sum/number of variables 3. The attempt at a solution The average calculated was 26.60833333. And Since two variables have only two sig figs, I thought the answer should be 27. But it was a wrong answer. But the last part of question asked the answer to be within ± 0.0 mph. What does 'within ± 0.0 mph' means? No uncertainty? Or typo of 0.1 or 0.01? What should be the correct answer?
