Given : The temperature reading from a thermocouple placed in a constant-temperature medium is normally distributed with mean
, the actual temperature of the medium, and standard deviation
.
Let X be the random variable that represents the reading of the thermometer.
Confidence level : 
We know that the z-value for 95% confidence interval is 1.96.
Then, we have

But all readings are within 0.6° of
.
So,

Hence, the required standard deviation will be
The answer is
P= -20
