If we add counts from two nonoverlapping areas, we are just counting the successes in a larger area. That count still meets the conditions of the Poisson setting. If the individual areas were equal in size, our unit of measure doubles, resulting in the mean of the new count being twice as large.Is the Large Counts condition met in this case?

If there is evidence that the percentage differs significantly from this target, then adjustments will be made to the game.1. Large Counts Condition: - In order to perform a chi-square goodness-of-fit test, each expected count in the contingency table should be at least 5, according to the large counts condition. - Since Miriam has a 10-sided die, there are 10 possible outcomes. - To ensure each expected count is at least 5, she needs a total of at least rolls. 2.Count cells in range1 that meet criteria1. By default, the COUNTIFS function applies AND logic. When you supply multiple conditions, ALL conditions must match in order to generate a count: =COUNTIFS(range1,criteria1,range1,criteria2) Count where range1 meets criteria1 AND range1 meets criteria2.
