The state’s Gaming Control Board does random inspections of casino games. An inspector observed 40 spins of the roulette wheel in a certain casino, and she recorded whether the result was a red number ("r") or a black number ("b"). (Assume that none of these results was a "0" or "00," which are green numbers.) Her observations are given below (the first row has the first 20 observations, and the second row has the next 20 observations). At the 0.05 significance level, test the claim that the red and black numbers occur in a random order. b r r b b r b r b r b r r b r b b b b b r r r r r r b r r r b r b r r r b r b b Identify the value of the TEST STATISTIC used in the hypothesis test of this claim.
