Organic chemists often purify organic compounds by a method known as fractional crystallization. one chemist prepared ten 4.85-g quantities of aniline and purified it to acetanilide. the following dry yields were recorded.
3.83 3.78 3.86 3.83 3.90 3.35 3.61 4.03 3.71 3.85
estimate the mean grams of acetanilide that can be recovered from an initial amount of 4.85 g of aniline. use a 95% confidence interval. (round your answers to three decimal places.)
