The Department of Transportation wishes to choose between two alternative accident prevention programs. It has identified three benefits to be gained from such programs:
1.
Reduced property damage, both to the vehicles involved in an accident and to other property (e.g., real estate that may be damaged at the scene of an accident)
2.
Reduced injuries
3.
Reduced fatalities
The department’s experts are willing to provide dollar estimates of property damage savings that are expected to accrue from any program, but they will estimate only the number of injuries and fatalities that may be averted.
The first program is relatively moderate in its costs and will be concentrated in a large city. It involves upgrading traffic signals, improving road markers, and repaving some potholed streets. Because of the concentration and value of property in the city, savings from reduced property damage are expected to be substantial. Likewise, a moderate number of traffic-related deaths and…

A government agency provides the number of miles that residents of the 75 largest metropolitan areas travel per day in a car. Suppose that for a simple random sample of 50 City A residents the mean is 22.9 miles a day and the standard deviation is 8.7 miles a day, and for an independent simple random sample of 40 City B residents the mean is 18.6 miles a day and the standard deviation is 7.7 miles a day.
(a)
What is the point estimate of the difference between the mean number of miles that City A residents travel per day and the mean number of miles that City B residents travel per day? (Use City A − City B.)

- The regional transit authority for a major metropolitan area wants to determine whether there is a relationship between the age of a bus and the annual maintenance cost. A sample of 10 buses resulted in the following data: Develop a scatter chart for these data. What does the scatter chart indicate about the relationship between age of a bus and the annual maintenance cost? Use the data to develop an estimated regression equation that could be used to predict the annual maintenance cost given the age of the bus. What is the estimated regression model? Test whether each of the regression parameters β0 and β1 is equal to zero at a 0.05 level of significance. What are the correct interpretations of the estimated regression parameters? Are these interpretations reasonable? How much of the variation in the sample values of annual maintenance cost does the model you estimated in part (b) explain?

The purpose of the study was to identify the most vulnerable sections of each plane and then take steps to reinforce those sections to improve pilot safety and airplane durability. The data gathered by the U.S. military showed that certain sections of its combat-tested fighter planes were consistently hit more often with enemy fire than other sections of the plane. Required: 1. Would you recommend reinforcing the sections of the plane that were hit most often by enemy fire, or would you reinforce the sections that were hit less frequently by enemy fire? Why? 2.
