A wine merchant receives regular shipments of cases of wine from New Zealand and records if any particular shipment was damaged (D) or acceptable (A). The merchant inspects his records for a series of 25 shipments to determine if there is a pattern to damage. The sequence of acceptable and damaged shipments were as follows:
A, D, D, D, A, A, A, A, A, D, D, A, A, D, D, D, D, A, D, D, A, A, A, A, A
Test if the sequence is random.
