I have the most of answer for this case but I need it to be business report
I need to make 6 different reports for this case for me and 5 of my friends.
It have to be totally different we are in the same class with the same teacher
I attached the data set and I attached two answers you can use them
I need a business report not just answer the questions:
The business report has:
1- Introduction / summary
2- Result / finding/ analysis
3- Conclusion
Interpret your findings from parts (a), (b), and (c) in a brief report.
- Develop a regression equation that expresses the relationship between age of the bus and maintenance. The age of the bus is the independent variable.
- a) Draw a scatter diagram. What does this diagram suggest as to the relationship between the two variables? Is it direct or indirect? Does it appear to be strong or weak?
- b) Develop a regression equation. How much does an additional year add to the maintenance cost. What is the estimated maintenance cost for a 10-year-old bus?
- c) Conduct a test of hypothesis to determine whether the slope of the regression line is greater than zero. Use the .05 significance level.
