I have a chart that has 4 columns across the top and 33 going down. The colunms on the top read: predicted number, selected number, (col 1 - col2)^2, and the mean of x. Their are 32 predicted numbers and 33 selected numbers. I need to fill in the column that says the mean of x but I am not sure how to do this.

predicted # = 5
Selected # = -2
(col 1 - col 2)^2 = 49
How would I find the mean for this column?
