Question:

9.55 In studying the properties of a certain type of resistor, the actual resistances produced were measured on a sample of 15 such resistors.

These resistances had a mean of 9.8 ohms and a standard deviation of 0.5 ohm. One resistor of this type is to be used in a circuit. Find a 95%

prediction interval for the resistance it will produce.
