The owner of the St. Paul Motor Inn in Minnesota is expanding the property and wants to install a new indoor swimming pool. To prevent heat loss, the owner plans to install the pool in as air-tight an enclosure as possible. As the facilities manager at the inn, you have been researching the swimming pools and pool heaters on the market. Based on what you've learned, you decide to recommend that the property should not purchase a directly fired heater for the new indoor pool, because directly fired water heaters:a. cause algae overgrowth, which leads to severe maintenance problems. b. cannot maintain a warm-enough pool temperature in your cold northern climate. c. have been blamed for incidents of carbon monoxide poisoning when used for indoor pools. d. are likely to provide uneven heating of the pool water, which would make swimmers uncomfortable.

An important application of regression analysis in accounting is in the estimation of cost. by collecting data on volume and cost and using the least squares method to develop an estimated regression equation relating volume and cost, an accountant can estimate the cost associated with a particular manufacturing volume. consider the following sample of production volumes and total cost data for a manufacturing operation. production volume (units) total cost ($) 400 4000 450 5000 550 5400 600 5900 700 6400 750 7000 compute b 1 and b 0 (to 2 decimals if necessary). b 1 b 0 complete the estimated regression equation (to 2 decimals if necessary). = + x what is the variable cost per unit produced (to 1 decimal)? $ compute the coefficient of determination (to 4 decimals). note: report r 2 between 0 and 1. r 2 = what percentage of the variation in total cost can be explained by the production volume (to 2 decimals)? % the company's production schedule shows 500 units must be produced next month. what is the estimated total cost for this operation (to 2 decimals)? $
