Waterbury Insurance Company wants to study the relationship between the amount of fire damage and the distance between the burning house and the nearest fire station. This information will be used in setting rates for insurance coverage. For a sample of 30 claims for the last year, the director of the actuarial department determined the distance from the fire station (x) and the amount of fire damage, in thousands of dollars (y). The MegaStat output is reported below.

A 10-year study conducted by the American Heart Association provided data on how age, blood pressure, and smoking relate to the risk of strokes. Data from a portion of this study follow. Risk is interpreted as the probability (times 100) that a person will have a stroke over the next 10-year period. For the smoker variable, 1 indicates a smoker and 0 indicates a nonsmoker.

The Department of Energy and the U.S. Environmental Protection Agency's 2012 Fuel Economy Guide provides fuel efficiency data for 2012 model year cars and trucks.† The file named CarMileage provides a portion of the data for 309 cars. The column labeled Size identifies the size of the car (Compact, Midsize, and Large) and the column labeled Hwy MPG shows the fuel efficiency rating for highway driving in terms of miles per gallon. Use α = 0.05 and test for any significant difference in the mean fuel efficiency rating for highway driving among the three sizes of cars. (Hint: you will need to re-organize the data to create indicator variables for the qualitative data).
Find the value of the test statistic for the overall model. (Round your answer to two decimal places.)

You have entered a model rocket contest with your friend, Tiffany. You have been working on a pressurized rocket filled with nitrous oxide. Tiffany has determined the minimum atmospheric pressure at which the rocket fuel is stable. Based not hat value, and the equations given below, your task is to determine the optimum launch angle and initial velocity to maximize flight time. The goal is to re-use your rocket capsule, so you really want to avoid a fuel explosion.
The atmospheric pressure varies with elevation according to the equation: P(h)= 14.7e−h/10. where p is the pressure in psi and h, is an elevation in miles above sea levels. The height (in feet) of a rocket launched at an angle α degrees with the horizontal and an initial velocity, vo in feet/second, t seconds after launch is given by the equation h(t)=-16t^2+vo*t*sin(α).
1) If Tiffany has determined that the minimum safe pressure is 11 pounds per square inch, at what altitude will the rocket explode? Report your result in feet. Round to the nearest foot.
2) If the angle of launch is33o, with an initial velocity of 1,648 what is the minimum atmospheric pressure exerted on the rocket during its flight? Report your answer to one decimal place. Under these conditions, will the rocket explode during its flight?
3) If the angle of launch is32o, with an initial velocity of 1,908 what is the minimum atmospheric pressure exerted on the rocket during its flight? Report your answer to one decimal place. Under these conditions, will the rocket explode during its flight?
4) Tiffany has revisited her calculation and has now concluded that the minimum safe pressure for the fuel is 9 psi. What is the maximum height your rocket can achieve without exploding in flight? Report your answer in feet to the nearest foot.
5) Tiffany has (once again) checked her calculations, and you have verified with her that the safe pressure for your fuel is 9 and the fuel capsule holds enough fuel to produce an initial velocity of 2,169 feet per second. What launch angle will you use so that your rocket achieves the maximum safe altitude? Round your answer to the nearest tenth of a degree.

James, a buyer at EZ Tech, a Alaska-based purveyor of generators for people in remote areas, was doing some number crunching. EZ Tech was reevaluating its suppliers for a key component of the generator, the generator frame. After some extensive evaluation, James had narrowed it down to two suppliers and he would source from the one with the lowest total cost, everything else held equal. Given the following information, use total cost analysis to determine which supplier, is more cost-effective for EZ Tech. Late delivery of the generator frame results in either a lost sale (thus lost profit) or a customer backorder (each time there is a backorder, it costs $195). Assume for the cost comparison that order quantity is 2,800 units and that the annual requirement (forecast) is 74,000 units. For purposes of calculating quality problems, James uses the expected invoice amount as a base. What should James do? Enter as ###,###. Enter negative numbers as -###,###.

42.A rail road is being proposed by the government to join two neighboring cities. The rail road will significantly reduce the travel time between the two cities. The only concern is that to set up the infrastructure for the rail road, approximately ten square miles of forests will need to be cleared. The forest is known for its flora and fauna and regularly attracts people from all over the country. Any construction activity in the forest would deprive future generations of this rich heritage. Thus the plan for the proposed rail road has been shelved because of the idea that the environment should be protected so that future generations may live in it, and have the choices as individuals have today. The above is an example of:
Select one:
a. social fairness.
b. an aesthetic argument.
c. an environmental impact statement.
d. incentives.
e. externalities.

Using the following case, describe how you would set up a program for young boy Jonathon who is watching too much T.V. and not getting his homework done, by using principles from operant conditioning (behavior modification). Be sure to include all of he tasks you would use before getting started. Determine the target behavior you would seek to change. include techniques that both increase and decrease the target behavior and those behaviors closely associated with the target behavior.
Jonathon is an eight-year-old boy. He is in the third grade and Bonneville Elementary School in Salt Lake County. He is the middle of three children. His older brother is age l l and his younger sister is age four. All three children live with their biological mother. Their parents divorced a year ago.
The children's father, Marquis, has a new partner and they live in an apartment approximately 15 miles from Jonathon, his mom, and his siblings. His mother is not seeing anyone at this time, so her evenings are spent at home with the children. She is, however, employed outside of the home and works as a clerk at a local convenience store.
Once a week, and every other weekend, the kids go to their father's house. Jonathon has begun complaining about being there as he reports it is not much fun because his father is "never there". He indicated that his dad's girlfriend isn't very friendly and that she orders Jonathon and siblings around all of the time.
Jonathon did well is school, until his parents began to have relationship problems. His mom especially noticed a change in his grades after his father moved out of the house, just over a year ago. Prior to that, he was earning A and B grades and seemed to enjoy his teachers and classmates.
He has been assessed and does not have any neurological problems or learning disorders. As the school social worker, you have been asked to help Jonathon by setting up a behavioral program that will improve his grades. Your assignment is to set up a program that addresses his study habits. He has been watching TV excessively, according to his mother, and he his neglecting to do his homework. As a result, he is getting D and F grades in his classes
