STAT 212 Business Statistics II 6 4. (10 marks) The data in the table below represent the mean price for three types of energy products in the US on each of the one- thirds period of the year (every four-month period) from 2003 to 2006. Included are prices of Electricity (\$ per 500 kWH), natural gas (\$ per 40 therms), and fuel oil (\$ per gallon) and their respective consumption Amounts. Energy Prices Consumption Amounts Year Period Electric price Natural Gas price Fuel Oil price Electric (kWH) Natural Gas (therms) Fuel Oil (gallons) First (F) 48.87 29.87 0.91 6450 1010 250 Middle(M) 48.54 29.57 1.01 6400 1000 260 2003 Last(L) 49.25 32.90 1.14 6330 990 255 F 46.40 31.44 0.97 5200 980 280 2004 M 45.06 30.70 0.83 5140 970 275 L 45.21 31.66 1.19 5680 1050 330 F 47.47 49.73 1.51 5870 1030 315 2005 M 47.87 36.32 1.12 5550 980 390 L 47.66 40.23 1.40 5700 1020 375 F 49.16 46.05 1.51 5280 940 360 2006 M 50.85 50.93 1.86 5300 950 385 L 57.22 66.40 2.42 5000 960 400

STAT 212 Business Statistics II 7 a. Based on the period F of 2005, compute the simple price index number of electricity for the period F of 2003, and interpret it. Interpretation b. Based on the first period of 2003, compute the Laspeyres index of the Energy prices in the first period of 2004 and interpret it. Interpretation c. Based on the first period of 2003, compute the Paasche index of the Energy prices in the first period of 2004 and interpret it. Interpretation d. Based on period L of 2003, compute the unweighted aggregate price index number of Energy prices in the last period L of 2005 and interpret it. Interpretation e. The single-exponential smoothing forecast for period F of 2003, using α =0.4 f. With the regression model Y= 45.698+0.451X, forecast the price of electricity in the period M of 2003 using a doubleexponential smoothing method with a trend-smoothing constant of 0.3 and a constant-process smoothing constant of 0.4 Year 2002 2003 2004 2005 2006 CPI 100 103.9 107.6 109.6 113.6 g. Assuming the same CPI index can be used within the same year, find the deflated price of electricity in period F on 2005 and period M of 2006.
