Can someone answer the question 6 to 9 only 3 questions asap

The pay for some jobs fluctuates more than the pay for others. You can use the Wolfram Alpha search engine in order to research demand for and pay for many occupations. For this project, we will compare the pay between teachers and firemen. Search Wolfram Alpha for: teacher, fireman 1. In what year was the most recent data collected? 2009 2. How many people were employed in each occupation? US education, training, and library occupations:_1.5443 million_US fire fighters: 305 500 people 3. What was the mean salary for each occupation? US education, training, and library occupations: $53 150 per year us fire fighters: $47270 per year 4. What was the median salary for each occupation? US education, training, and library occupations: $50510 per year us fire fighters: $44260 per year 5. The graph compares median wages of each occupation. Why was a better choice than mean wage? Ans)The median is not significantly changed by this one "outlier," while the mean becomes a wage that no one earns and also it is ineffective to use method that is so strongly affected by atypical salaries? 6. If you assume that the change in median salary is linear, then you can find the equation that estimates annual median salary by applying the yearly change in median wage. Find, and graph, the equations that represent the median salary per year for each occupation. Let x represent the year after 2000 and let y represent the median salary for that year. US education, training, and library occupations: US fire fighters: 7. How does your graph match up with the one shown? Answers vary 8. Use the equations from #6 to see which year the median salaries were equal. How much was the median salary in that year? 9. A more accurate linear model might be found by selecting two points on each line and finding the equation of the straight line through them. Use the graph given by Wolfram Alpha to estimate the location of two points on each line. Give the equations: US education, training, and library occupations: US fire fighters: Suggestions: Select two other occupations that you may be considering. Compare the demand for those jobs to see which has the better outlook. Compare the annual pay for those jobs
