Topic 6 Assignment Submitted 7 Problem 18-14 (Algo) Demand for stereo headphones and MP3 players for Joggers has caused Nina Industries to grow almost 50 percent over the past year. The number of joggers continues to expand, so Nina expects demand for headsets to also expand, because, as yet, no safety laws have been passed to prevent Joggers from wearing them. Demand for the players for last year was as follows: 0.23/3 points awarded MONTH DEMAND (UNITS) January 4, 160 Scored February 4, 260 March 8,960 April 4,360 May 4,960 June 1, 666 Book July , 260 August 1, 860 September 5,360 october 5, 660 Print November , 260 December 5,960 References a. Using linear regression analysis, what would you estimate demand to be for each month next year? (Do not round Intermedlate calculations. Round your answers to 2 decimal places.)
