A new 1.5 volt battery has an actual voltage that is uniformly distributed between 1.43 and 1.60 volts. Estimate the probability that the sum of the voltages from 120 new batteries lies between 180 and 182 volts.

Question

anonymous · Answer

I don't even know how to go about solving this.

perl · Answer

well the probability that one battery lies between 180 and 182 volts, you can do that, right?

anonymous · Answer

It's just a normal distribution right?

anonymous · Answer

FInd probability of 182 and 180 and subtract the two areas right?

anonymous · Answer

normal $\not=$ uniform

anonymous · Answer

A bell curve is uniform though.

anonymous · Answer

There isn't skewness implied here.
