A potential investor conducted a 144 day survey in each theater in order to determine the difference between the average daily attendance at the North Mall and South Mall theaters. The North Mall Theater averaged 630 patrons per day; while the South Mall Theater averaged 598 patrons per day. From past information, it is known that the variance in attendance for North Mall is 1,000; while the variance for the South Mall is 1,304.
