Electrical Resistors

I really need help with this problem. Thank you!

A certain machine makes electrical resistors having a mean resistance of 40 ohms and a standard deviation of 2 ohms. What is the probability that a random sample of 50 resistors has a combined resistance of more than 2010 ohms?

Solution Summary

This solution contains step-by-step calculations to determine the probability that a random sample of 50 resistors has a combined resistance of more than 2010 ohms.
