The resistances of carbon resistors of 1500 ohm nominal value are normally distributed with µ = 1500 and standard deviation = 200.

a. What proportion of resistors is expected to have resistance greater than 1150 ohm?

b. Within plus and minus what amount around the mean do 80 percent of resistances fall?
