The leading digits in actual data, such as stock prices, population numbers, death rates, and lengths of rivers, do not occur randomly as one might suppose, but instead follow a distribution according to Benford€™s law. Below is the probability distribution for the leading digits in real-life lists of data. Calculate the mean for the distribution.
