Answer: 0.3061.
Step-by-step explanation:
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
