Question
The initial temperature of a certain container is measured to be To = 20°C. The ambient
temperature is measured to be Ta = 4°C. An engineer uses Newton's law of cooling to
compute the time needed to cool the container to a temperature of 10°C. Taking into
account the physical properties of the container, this time (in minutes) is computed to be
T = 401n
10 – T
Assume that the temperature measurements To and T, are unbiased and come from normal
populations with standard deviation 0.1 °C.
Generate an appropriate simulated sample of values T*. Is it reasonable to assume that
T is normally distributed?
a.
b.
Use the simulated sample to estimate the standard deviation of T.
If appropriate, use the normal curve to find a 95% confidence interval for the time
needed to cool the container to a temperature of 10°C.
C.
