Statistics(Please help)
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.
Column 1 reads :
predicted # = 5
Selected # = 2
(col 1  col 2)^2 = 49
How would I find the mean for this column?
