A mоvie theаter chаin, MаrkusFun Cinema, cоnducts a simple оbservation: over two months, it finds that the two theaters with the highest-rated customer satisfaction scores also have the highest average ticket prices. The CEO concludes that high prices cause higher satisfaction by attracting a more discerning, satisfied clientele and orders a price increase across all locations (Great idea?). A. Using the three conditions required to establish causality (Consistent variation (correlation), Temporal Sequence, and Elimination of Other Causes), critique the CEO's conclusion. (3 pts) B. Identify the most likely third variable that was not eliminated (a plausible cause) and explain why the observed correlation is likely spurious. (2 pts) C. Suppose the CEO asks your opinion before hiking prices at all locations. How would you test causality in this example and be more confident about higher prices contributing to higher satisfaction?( 3pts)
