You may attempt using the following keying sequences and see if they work out properly:


=================================================================


1) Press 2 M + 4 M + 6 M + 8 M + 10 M + to input all 5 data.


2) Press SHIFT 2 1 EXE and the Mean is printed out.


3) Press SHIFT 2 2 EXE and the S.D. is printed out.


=================================================================


Hope I can help you.
