For the following exercises, consider the scenario: The population of a city increased steadily over a ten-year span. The following ordered pairs shows the population and the year over the ten-year span, (population, year) for specific recorded years: (47750, 2001), (48000, 2003), (48250, 2004), (48450, 2005), (49100, 2009) a. Use linear regression to determine a function y, where the year depends no the population. Round to three decimal places of accuracy. b. Predict when the population will hit 54000. In the year

Consider the regression equation log Yi= log 3.03+1.3 log X1i+1.78 log X2i. a. Predict the value of Y when X1=7.9 and X2=5.4. b. Interpret the meaning of the regression coefficients b0, b1, and b2.
The following table shows the rate R of vehicular involvement in traffic accidents (per 100,000,000 vehicle-miles) as a function of vehicular speed s, in miles per hour, for commercial vehicles driving at night on urban streets. Speed s Accident rate R 20 1600 25 700 30 350 35 250 40 650 45 1350 (a) Use regression to find a quadratic model for the data. (Round the regression parameters to two decimal places.) (b) Calculate R(65). (Round your answer to two decimal places.)
Consider the following estimated regression model relating annual salary to years of education and work experience. Estimated Salary = 11,433.70 + 3312.68(Education) + 819.54 (Experience ) Suppose an employee with 7 years of education has been with the company for 5 years (note that education years are the number of years after 8th grade). According to this model, what is his estimated annual salary? 囲 Tables E Keypad Answer Keyboard Shortcuts
c. Use f(x) to estimate the average salary in 2020. The average salary in 2020 will be thousands. (Type an integer rounded to the nearest whole thousands.) d. The average salary in NFL Jn 1997 was reported to be $736,700. How does this compare with the value given by the model? A. The model does not give a value for 1997. B. The actual value is greater than the model. OC. The actual value is less than the model. OD. The actual value is the same as the model.
