1. Sampling methods have a biased and unbiased side to them; to make an inference for the population, methods should be representative.
2. To make an inference with multiple samples, you can find the mean of the data you collected. If you 13, 14, and 15 different people answer in three different surveys, you would find the mean of that for an accurate sample. You could also use a proportion to estimate.
3. Another way to solve a proportion is to do cross multiplication.
