Question: A cereal box currently advertises that it includes one of two collectible miniature (matchbox-sized) cars. The plant manager where the cereal is being processed and packaged knows the machinery which placed the toy into the packages malfunctioned, but was unsure if the randomness was compromised. She tests a randomly selected sequence of 24 boxes. The results were as follows, read across rows, with cereal boxes containing the first of the two cars labeled as A and the those containing the second of the two marked as B:

At the 5% level of significance, are the two being distributed randomly into the boxes, according to the available evidence? [COMMENTS & HINTS: Try the Runs Test for Randomness, using the appropriate table, MGT 5007-16-22, which provides critical values for an alpha of 0.05.]
