The pressure of air (in MPa) entering a compressor is measured to be X = 8.5 ± 0.2, and the pressure of the air leaving the compressor is measured to be Y = 21.2 ± 0.3. The intermediate pressure is therefore measured to be P = √XY = 13.42. Assume that X and Y come from normal populations and are unbiased.
a. From what distributions is it appropriate to simulate values X∗ and Y∗?
b. Generate simulated samples of values X∗, Y∗, and P∗.
c. Use the simulated sample to estimate the standard deviation of P.
d. Construct a normal probability plot for the values P∗. Is it reasonable to assume that P is approximately normally distributed?
e. If appropriate, use the normal curve to find a 95% confidence interval for the intermediate pressure.
