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: DEMAND (UNITS) 4,000 4,100 3,800 4,200 4,850 4,500 5,150 4,750 5,250 5,550 6,150 5,850 MONTH January February March April May June July August September October November December a. Using linear regression analysis, what would you estimate demand to be for each month next year? (Do not round intermediate calculations. Round your answers to 2 decimal places.) Month Forecast January February March April May June July August September October November December
