Water at 100$^{\circ} \mathrm{C}$, quality 50% in a rigid box is heated to 110$^{\circ} \mathrm{C}$. How do the properties (P, v, x, u, and s) change (increase, stay about the same, or decrease)?

Which of the fo llowing is/ are simple random samples? As Lipitor pills are being manufac tured, a quality control plan is to select every 500th pill and test it to confirm that it contains 80 mg of atorvastatin.

Determine the volume, in $\mathrm{ft}^{3}$, of 2 lb of a two-phase liquid–vapor mixture of Refrigerant 134A at $40^{\circ} \mathrm{F}$ with a quality of 20$\%$. What is the pressure, in $\mathrm{lbf/in.}^{2}$?

What patterns of institutional processes and organisational structures result from globalisation? Why is it required to implement these new systems and procedures? How do they affect people's quality of life, either positively or negatively?

Ammonia at 0$^{\circ} \mathrm{C}$ with a quality of 60% is contained in a rigid 200-L tank. The tank and ammonia are now heated to a final pressure of 1 MPa. Determine the heat transfer for the process.

A quality-control technician must select a sample of 10 dresses from a production lot of 74 couture dresses. How many different samples are possible? Express your answer in terms of factorials.

Determine the specific volume for R-410a at these states:a. $-15^{\circ} \mathrm{C}$, 400 kPab. $20^{\circ} \mathrm{C}$, 1500 kPac. $20^{\circ} \mathrm{C}$, quality 25%

What costs of quality were highlighted in the opening case study? How can Delta Air Lines justify spending $100 million to reengineer the baggage-handling process at just one airport?

In Exercises $1$ through $10$, the probability density function for a continuous random variable $X$ is given. In each case, find the expected value $E(X)$ and the variance $\operatorname{Var}(X)$ of $X$.

$$f(x)= \begin{cases}\frac{3}{32}\left(4 x-x^2\right) & \text { if } 0 \leq x \leq 4 \\ 0 & \text { otherwise }\end{cases}$$

A high-quality diamond may be quite clear and colorless, transmitting all visible wavelengths with little absorption. Describe how it can sparkle with flashes of brilliant color when illuminated by white light.

A distribution that has been used to model tolerance levels in bioassays is the logistic distribution with parameters $\alpha$ and $\beta.$ The cumulative distribution function of the logistic distribution is $F(x)=\left[1+e^{-(x-\alpha) / \beta}\right]^{-1}$ The parameter $\alpha$ may be any real number; the parameter $\beta$ may be any positive number. Let X be a random variable with this distribution. a. Find the probability density function $f_{x}(x).$ b. Show that $f_{x}(x)$ is symmetric around $\alpha,$ that is $f_{X}(\alpha-x)=f_{X}(\alpha+x)$ for all x. c. Explain why the symmetry described in part (b) shows that $\mu_{x}=\alpha.$ You may assume that $\mu_{x}$ exists.
