A computer selects a number XX from 4 to 9 randomly and uniformly. Round all answers to 4 decimal places where possible.
- What is the distribution of XX? XX ~ U(,)
- Suppose that the computer randomly picks 36 such numbers. What is the distribution of ¯xx¯ for this selection of numbers. ¯xx¯ ~ N(,)
- What is the probability that the average of 36 numbers will be less than 6?

You are heating airflow in a long, round tube. The tube is
irradiated uniformly, on all sides, with a constant thermal heat
flux q". Inside the tube, the air flows with a known heat flux mdot
and constant, known properties. The tube has a length L and a
diameter D. This is your baseline case. You then add a helical coil
inside the tube that stirs up the airflow and doubles the value of
h over the baseline case. a)...
