The expected value for the cell marked with "XX" can be calculated by multiplying the row total by the column total and dividing by the total count.
In this case, the row total is 19, the column total is 45, and the total count is 77.
Expected Value = (Row Total * Column Total) / Total Count
Expected Value = (19 * 45) / 77
Expected Value = 855 / 77
Expected Value = 11.104
Therefore, the expected value for the cell marked with "XX" is 11.104, which is closest to option C (11.104).
In this case, the row total is 19, the column total is 45, and the total count is 77.
Expected Value = (Row Total * Column Total) / Total Count
Expected Value = (19 * 45) / 77
Expected Value = 855 / 77
Expected Value = 11.104
Therefore, the expected value for the cell marked with "XX" is 11.104, which is closest to option C (11.104).
