For each of the following situations, decide what sampling method you would use. Provide an explanation of why you selected a particular method of sampling. a. Alarge automotive companywants to upgrade the software on its notebook computers. A survey of 1,500 employees will request information concerning frequently used software applications such as spreadsheets,word processing, e-mail, Internet access, statistical data processing, and so on.Alist of employees with their job categories is available. b. A hospital is interested in what types of patients make use of their emergency room facilities. It is decided to sample 10% of all patients arriving at the emergency room for the next month and record their demographic information along with type of service required, the amount of time patient waits prior to examination, and the amount of time needed for the doctor to assess the patient’s problem.

You are working in the emergency department (ED) of a community hospital when the ambulance arrives with A.N., an $18$-year-old woman who was caught in a house fire. She was sleeping when the fire started and managed to make her way out of the house through thick smoke. The emergency medical system crew initiated humidified oxygen at $15 \mathrm{~L} / \mathrm{min}$ per nonrebreather mask and started a $16$-gauge IV with lactated Ringer's solution. On arrival to the ED, her vital signs are $100/66, 125, 34$, $\mathrm{SaO}_2 93 \%$. An additional $16$-gauge IV is inserted. She appears anxious and in pain.

A.N. has one area of circumferential burns on her right lower leg. What complication is she in danger of developing, and how will you monitor for it?

A car can be braked to a stop from the autobahn-like speed of $200 \mathrm{~km} / \mathrm{h}$ in $170 \mathrm{~m}$. Assume that the acceleration is constant. $T_b$ is required time for the braking. Your reaction time $T_r$ is the time you require to perceive an emergency, move your foot to the brake, and begin the braking. If $T_r=400 \mathrm{~ms}$, then what is $T_b$ in terms of $T_r$ ?

Passengers exiting a plane during an emergency use rough slides inclined at $45 ^ { \circ }$ to do so. An elderly woman has an inertia of 60 kg and is helped by pushing on her horizontally with 200 N force as she slides from a height of 20 m. (a) Calculate the work done on her by the frictional force. (b) Calculate her speed at the bottom of the ramp. The coefficient of kinetic friction is 0.05.

It is said that to meet Postal Service requirements, footwear must have a coefficient of static friction of $0.5$ or more on a specified tile surface. A typical athletic shoe has a coefficient of $0.800$. In an emergency, what is the minimum time interval in which a person starting from rest can move $3.00 \mathrm{~m}$ on a tile surface if she is wearing a typical athletic shoe?

A.N. is concerned about visible scars. What will you tell her to allay her fears?

A plane leaves the airport in Galisteo and flies 170 km at $68.0^{\circ}$ east of north; then it changes direction to fly 230 km at $36.0^{\circ}$ south of east, after which it makes an immediate emergency landing in a pasture. When the airport sends out a rescue crew, in which direction and how far should this crew fly to go directly to this plane?

A hiking party is lost in a national park. Two rangeri stations have received an emergency SOS signal from the party. Station B is $75$ miles due east of Station A. The bearing from Station A to the signal is $S 60^\circ E$ and the bearing from Station B to the signal is $S 75^\circ W$.

Find the distance from each station to the SOS signal.

Color coding is often used in manufacturing operations to display production status or to identify/prioritize materials. For example, suppose "green" status indicates that an assembly line is operating normally, "yellow" indicates it is down waiting on personnel for set up or repair, "blue" indicates it is down waiting on materials to be delivered, and "red" indicates an emergency condition. Management has set realistic goals whereby the assembly line should be operating normally $80 \%$ of the time, waiting on personnel $9 \%$ of the time, waiting on materials $9 \%$ of the time, and in an emergency condition $2 \%$ of the time. Based on 250 recent status records, the status was green 185 times, yellow 24 times, blue 32 times, and red 9 times.

c. Are management's goals being met at $\alpha=0.05$ ? Will your conclusion change at $\alpha=$ 0.01
