To find the percent error, we need to calculate the average of the reported ticket sales and compare it with the actual average of 1200 tickets.
Sum of reported ticket sales = 1100 + 1000 + 950 = 3050
Average of reported ticket sales = 3050 / 3 = 1016.67
Percent error = |average of reported ticket sales - actual average| / actual average * 100
Percent error = |1016.67 - 1200| / 1200 * 100
Percent error = 183.33 / 1200 * 100
Rounding to the nearest whole number, the percent error is 79%.
