The formula for calculating the margin of error is 1.96 * standard deviation / square root of sample size. Since we want the margin of error to be less than or equal to 1, we can set up the inequality 1.96 * standard deviation / square root of sample size ≤ 1. Solving for the sample size, we get approximately 15.6, which rounds up to 16. Therefore, we would need a sample size of approximately 16 to be 95% confident that we wouldn't make an error of more than 1 unit in our estimate of F1F1F1S1F1F1F10 for F1F1F1S1F1F1F10 = 2.
