Assume a normal distribution with known population variance. Calculate the LCL and UCL for each of the following.

a. $\bar{x}=50 ; n=64 ; \sigma=40 ; \alpha=0.05$

b. $\bar{x}=85 ; n=225 ; \sigma^2=400 ; \alpha=0.01$

c. $\bar{x}=510 ; n=485 ; \sigma=50 ; \alpha=0.10$

A card is drawn at random from a regular deck of 52 cards. Find the probability of each event. A spade is drawn.

Solve. The length of a side of the base of a regular square pyramid is 6 in. and the height of the pyramid is 10 in. Find the volume of the pyramid.

"It is right to use anima ls for medical testing if it might save human lives." The General Social Survey asked 1152 adults to react to this statement. Here is the two-way table of the ir responses:

$$\begin{array}{l|rc} \hline \text { RESPONSE } & \text { MALE } & \text { FEMALE } \\ \hline \text { Strongly agree } & 76 & 59 \\ \hline \text { Agree } & 270 & 247 \\ \hline \text { Neither agree nor disagree } & 87 & 139 \\ \hline \text { Disagree } & 61 & 123 \\ \hline \text { Strongly disagree } & 22 & 68 \\ \hline \end{array}$$

How do the distributions of opinion differ between men and women?

A homeowner buys a new refrigerator and a new air conditioner. Which one of these devices would you expect to have a higher COP? Why?

Rotate the axes so that the new equation contains no xy-term. Analyze and graph the new equation. $x^{2}+4 x y+y^{2}-3=0$

A picture-framing company sells two types of glass: regular and nonglare. For a piece of nonglare glass, the charge is equal to the length of the longest side in inches multiplied by the rate $0.75 per inch. For what length will the charge for nonglare glass be the same as the charge for regular glass? What will the charge be? Explain your answers.

A dynamometer is a device used to measure torque and speed and to vary the load on rotating devices. The dynamometer operates as follows to control the amount of torque: A hydraulic actuator attached to the axle presses a tire against a rotating flywheel. The greater the displacement of the actuator, the greater the force that is applied to the rotating flywheel. A strain gage load cell senses the force. The displacement of the actuator is controlled by an electrically operated valve whose displacement regulates fluid flowing into the actuator. Draw a functional block diagram of a closed-loop system that uses the described dynamometer to regulate the force against the tire during testing. Show all signals and systems. Include amplifiers that power the valve, the valve, the actuator and load, and the tire.

Many traffic experts argue that the most important factor in accidents is not the average speed of cars but the amount of variation. Suppose that the speeds of a sample of 200 cars were taken over a stretch of highway that has seen numerous accidents. Compute the variance and standard deviation of the speeds, and interpret the results.
