Benford's law, also known as the first‑digit law, represents a probability distribution of the leading significant digits of numerical values in a data set. A leading significant digit is the first occurring non‑zero integer in a number. For example, the leading significant digit in the number 127127 is 11. Let this leading significant digit be denoted ?x. Benford's law notes that the frequencies of ?x in many datasets are approximated by the probability distribution shown in the table. ?x 11 22 33 44 55 66 77 88 99 ?(?)P(x) 0.3010.301 0.1760.176 0.1250.125 0.0970.097 0.0790.079 0.0670.067 0.0580.058 0.0510.051 0.0460.046 Determine ?(?)E(X), the expected value of the leading significant digit of a randomly selected data value in a dataset that behaves according to Benford's law? Please give your answer to the nearest three decimal places. ?(?)E(X) = Select the statement that best describes the interpretation of the expected value of the Benford's law…
