Sapling Homework Question 1B 27

Could someone explain how to arrive at the correct uncertainty in position? I used 10m/s as the uncertainty in speed because the problem said +/-5 and 8 as the mass to get 80*deltax >= h/(4pi) and got 6.59*10ˆ-37. I assume I got the uncertainty in velocity wrong but if so how would I get it correctly?

That is actually the correct answer, the solutions manual had an error in the calculations, so you got it right!
