As part of a study on transportation safety, the U.S. Department of Transportation collected data on the number of fatal accidents per 1000 licenses and the percentage of licensed drivers under the age of 21 in a sample of 42 cities. Data collected over a one-year period follow.

Please see the attached file for the table.

1. Write the regression equation.
2. Interpret the regression constant and regression coefficient.
3. Forecast a value for the dependent variable.
4. Conduct a test on the regression coefficient at an alpha level of .05.
5. Conduct a test on the overall significance of the regression equation.
6. Interpret the coefficient of determination.7. Are there any violations of the general linear model? Be specific.

This solution conducts a statistical analysis in an Excel file on the number of fatal accidents per 1000 licenses and the percentage of licensed drivers under the age of 21. The regression equation is determined, a forecast is given for the dependent variable and a test is conducted on the regression coefficient.

Let x be the age of licensed driver in years. Let y be the percentage of all fatalaccidents(for a given age)due to failure to yield the right of way. For example, the first data pair says that 5% pof all fatalaccidents involving 37year olds are due to failure to yield the right of way.
X: 37, 47, 57, 67, 77, 87
Y: 5, 8, 10 ,

A survey of 600 non-fatalaccidents showed that 278 involved the use of a cell phone.
If possible, construct a 99% confidence interval for the proportion of non-fatalaccidents that involved the use of a cell phone. Interpret the meaning of this interrval.

A bicycle safety organization claims that fatal bicycle accidents are uniformly distributed throughout the week. The table below shows the day of the week for which 778 randomly selected fatal bicycle accidents occurred. At ? = 0.10, can you reject the claim that the distribution is uniform?

Please give your opinion on the following article:
There were an estimated 6,356,000 car accidents in the US in 2000. There were about 3.2 million injuries and 35,875 people were killed in auto accidents in 2000 based on data collected by the Federal Highway Administration. There were an estimated 6,289,000 police-reported

The probability is 1 in 4,000,000 that a single auto trip in the United States will result in a fatality. Over a lifetime, an average U.S. driver takes 50,000 trips. (a) What is the probability of a fatal accident over a lifetime? (b) Why might the assumption of independence be violated? (c) Why might a driver be tempted not t

H0: Engaging in low-cost, high-risk activities improves airline safety.
Ha: Engaging in low-cost, high-risk enhancements do not improve airline safety.
A. Answering the Research Questions
Define the null and alternative hypotheses and state how t

The probability is 1 in 4,000,000 that a single auto trip in the U.S. will result in a fatality. Over a lifetime, an average U.S. driver takes 50,000 trips. (a) what is the probability of a fatal accident over a lifetime? Explain your reasoning carefully. Hint: Assume independent events. Why might the assumption of independence
