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
