In research on the quality of... blah blah. A) find Sll, Stt and Slt. Sum of L = 26.8, Sum of L^2 = 150.02, Sum of T = 47.2, Sum of Et^2 = 399.58, Sum of Lt = 237.07. I can identify to work out majority of the data, but can't work out how to find the Sum of Lt I tried Sum of L(26.8) x Sum of T (47.2) = 1264.96, eh? I just don't know to do it. Can someone please show me how to work out the Sum of Lt? Please do note the data below was used to calculate the Sums above.
