Question:
8.23 Resistors of a certain type have resistances that are approximately normally distributed with mean 200 ohms. Fifteen of these resistors are to be used in a circuit. The standard deviation of 12 measurements is 10 ohms.
a Find the probability that the average resistance of the 15 resistors is between 199 and 202 ohms.
b Find the probability that the total resistance of the 15 resistors does not exceed 5,100 ohms.
