- Physician Demand The demand for physicians is expected to increase in the future, as shown in the table. Source: Associa- tion of American Medical Colleges. Demand for Physicians (in thousands) Year 2006 680.5 2015 758.6 2020 805.8 2025 859.3 (a) Plot the data, letting t = 0 correspond to 2000. Does fit- ting an exponential curve to the data seem reasonable? (b) Use the data for 2006 and 2015 to find a function of the form f(1) = Ce" that goes through these two points. (c) Use your function from part (b) to predict the demand for physicians in 2020 and 2025. How well do these predic- tions fit the data? (d) If you have a graphing calculator or computer program with an exponential regression feature, use it to find an exponential function that approximately fits the data. How does this answer compare with the answer to part (b)?

Use the border crossings data below and a = = 0.3 and ẞ = 0.2. Truck Crossings Month February 113,691 March 139,204 April 121,498 May 127,511 June 131,500 July 105,245 August 126,606 Copy Data Step 2 of 2: Calculate the adjusted exponential smoothing forecast for September 2011. Assume the forecast component for February 2011 to be the actual truck crossing value minus the initial trend. Let the initial trend be 10,000 trucks. Round your answer to two decimal places.
