Studio XYZ knows that their films made an average of $45 million on opening weekends from 2003 - 2007. Did Studio XYZ films do better than the industry as a whole? Use your results to decide. HINT - Our initial assumption would be that Studio XYZ made the same amount on opening weekend as the industry as a whole, and we are interested in proving, if possible, that the industry average is lower than Studio XYZ's average. (Assume the population standard deviation is $9.71 million by previous knowledge.)
