1 grain = 103g
2kg = 2000g

Check the one-sided limits:


If <em>f(x)</em> is to be continuous at <em>x</em> = 5, then these two limits should have the same value, which means
5<em>k</em> = 200
<em>k</em> = 200/5
<em>k</em> = 40
You would be concluding that <span>the populations from which our samples come are different. I hope this helps.</span>
