What is the MEAN SQUARED (MS) for the ERROR term? 0.00043
What is the F Calculated value? F-Calculated
What is F Critical value (from the table)? 4.2600
Will you reject the null? Yes or No
Base on my calculations above, should I reject the Null? If so for what reason?"
If your F Calculated (which I don't see a number for) is greater than your F Critical, then you should reject the NULL hypothesis. That is also your reason. F Calc > F Crit.

The F Calc is 0.7629. So How do I write the justification on why I am rejecting the Null in non-statistical terms, where anyone could understand it?
Well, that would depend a lot on what you were measuring and what the null hypothesis was.
You could say something like "there is a statistically significant difference in the two machines." I can't do any better than that without knowing what the machines are measuring.
But, if F Calc is .76 and F Crit is 4.2, then you can't reject the NULL hypothesis because there is no statistically significant difference.
