Weber Valley Regional Hospital has collected data on all of its activities for the past 16 months. Data for cardiac nursing care follow: Y Cost X Hours of Nursing Care May Year 1 $59,600 1,400 June Year 1 57,150 1,350 July Year 1 61,110 1,460 August Year 1 65,800 1,600 69,500 1,700 September Year 1 October Year 1 64,250 1,550 November Year 1 52,000 1,200 December Year 1 66,000 1,600 January Year 2 83,000 1,800 February Year 2 66,550 1,330 March Year 2 79,500 1,700 April Year 2 76,000 1,600 May Year 2 68,500 1,400 June Year 2 73,150 1,550 July Year 2 73,175 1,505 August Year 2 66,150 1,290 In the computations below, use intercepts rounded to the nearest whole number and use X variable coefficients rounded to 2 decimal places. 1. Using the high-low method, calculate the variable rate per hour and the fixed cost for the nursing care activity. Enter negative answers with a minus sign. Y 2. Run a regression on the data, using hours of nursing care as the independent variable. Predict cost for the cardiac nursing care for September Year 2 if 1,400 hours of nursing care are forecast. If required, round your answer to the nearest dollar. Y = $ 3. Upon looking into the events that happened at the end of Year 1, you find that the cardiology ward bought a cardiac-monitoring machine for the nursing station. Administrators also decided to add a new supervisory position for the evening shift. Monthly depreciation on the monitor and the salary of the new supervisor together total $10,000. Now, run two regression equations, one for the observations from Year 1 and the second using only the observations for the eight months in Year 2. What is your predicted cost of the cardiac nursing care activity for September Year 2 if 1,400 hours of nursing care are forecast? When required, round your answer to two decimal places. Y=$1
