Explanation Given Information: The distribution of first digits of Good neighbor, Inc.’s tax returns is: y 1 2 3 4 5 6 7 8 9 P ( Y = y ) 0.28 0.16 0.10 0.11 0.07 0.09 0.05 0.07 0.07 The sample size is n = 400 . Consider the distribution of first digits of Good neighbor, Inc.’s tax returns: y 1 2 3 4 5 6 7 8 9 P ( Y = y ) 0.28 0.16 0.10 0.11 0.07 0.09 0.05 0.07 0.07 To compute the 95 % certainty compare the sum of squares of error (SSE) to the largest error that would have been expected to get by chance in 95 out of 100 selections of data. The biggest error is computed using the “chi-square” distribution. If the SSE is less than the chi-square value then 95 % certainty is not obtained. Compute the chi-squared value using MS-Excel by entering, " = CHISQ .INV .RT ( 0.05 , 8 ) " . Where 0.05 is 1 − 0 .95 denoting the 95 % certainty and 8 is the degrees of freedom = number of outcomes − 1 . Compute the SSE to determine how far a data value deviates from the value according to the Benford’s law using the formula, S S E = n [ P ( y 1 ) − P ( x 1 ) P ( x 1 ) + P ( y 2 ) − P ( x 2 ) P ( x 2 ) + ... + P ( y 9 ) − P ( x 9 ) P ( x 9 ) ] Where P ( y i ) are the probabilities in the Good are neighbor, Inc
