Why is N so large? (question 1,2)

Hi
In the lecture, the professor gave a rule of thumb that N>~10*Dv.c. in order to get a reasonable error.
But in these calculations, we see that N has to be much larger than that.
Why is so? Can anybody explain?

Thanks
Dan

These calculations use a bound that is admittedly very loose. The rule of thumb gives the practical version of it.
