It was discovered that first digits do not occur with equal frequency. Probabilities of occurrence to the first digit in a number are shown in the accompanying table. The probability distribution is now known as Benford's Law. For example, the following distribution represents the first digits in 188 allegedly fraudulent checks written to a bogus company by an employee attempting to embezzle funds from his employer. a) What is the test statistics? b) What is the p-value?
