A statistical program is recommended. Electric power consumption is measured in kilowatt-hours (kWh). The local utility company offers an interrupt program whereby commercial customers that participate receive favorable rates but must agree to cut back consumption if the utility requests them to do so. A certain company cuts back consumption at 12:00 noon Thursday. To assess the savings, the utility must estimate the company's usage without the interrupt. The period of interrupted service was from noon to 8:00 p.m. Data on electric power consumption for the previous 72 hours are available. Time Period Monday Tuesday Wednesday Thursday 12-4 a.m. 19,281 31,209 27,330 4-8 a.m. - 33,205 37,024 32,715 8-12 noon 99,516 119,968 152,465 12-4 p.m. 124,299 123,666 156,043 4-8 p.m. 113,545 111,717 128,889 8-12 midnight 41,300 48,112 73,923 (b) Compute seasonal indexes for the six 4-hour periods.
