Demand for stereo headphones and MP3 players for joggers has caused… 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: MONTHDEMAND (UNITS)  January4,170  February4,270  March3,970  April4,370  May4,970  June4,670  July5,270  August4,870  September5,370  October5,670  November6,270  December5,970    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.) b. To be reasonably confident of meeting demand, Nina decides to use 4 standard errors of estimate for safety. How many additional units should be held to meet this level of confidence? (Do not round intermediate calculations. Round your answer to the nearest whole number.)    Accounting Business Managerial Accounting MGT 655 Share QuestionEmailCopy link
