Electrical resistors have a design resistance. The resistors are produced by a machine with an output that is Normally distributed with mean 501 ohms and standard deviation 3 ohms. Resistance below 498 ohms and above 508 ohms are rejected. Find: ( The proportion that will be rejected: (4marks) (1) How much the standard deviation would need to be reduced (leaving the mean at 501 ohms) so that the proportion of rejected below 498 ohms would be halved.
