The mass (in kg) of a soil specimen is measured to be X =
Chapter 5, Problem 2E(choose chapter or problem)
The mass (in kg) of a soil specimen is measured to be X = 1.18 \(\pm\) 0.02. After the sample is dried in an oven, the mass of the dried soil is measured to be Y = 0.85 \(\pm\) 0.02. Assume that X and Y come from normal populations and are unbiased. The water content of the soil is measured to be
\(W=\frac{X-Y}{X}\)
a. From what distributions is it appropriate to simulate values X∗ and Y∗ ?
b. Generate simulated samples of values X∗ , Y∗ ,and W∗ .
c. Use the simulated sample to estimate the standard deviation of W.
d. Construct a normal probability plot for the values W∗ . Is it reasonable to assume that W is approximately normally distributed?
e. If appropriate, use the normal curve to find a 95% confidence interval for the water content.
