Use the sample of the greenhouse gas emissions of 32 different cars. (The amounts are in tons per year, expressed as CO2 equivalents.) Use a 0.05 significance level to test the claim that all cars have a mean greenhouse gas emission of 8.00 tons. Find the statistic, p-value and the critical value (or values). (I can ask for the satistic ,p value and critical value separately if needed) Data: Car GHG Acura RL 8.7 Acura TSX 7.2 Audi A6 7.7 BMW 525i 7.7 Buick LaCrosse 7.9 Cadillac STS 8.7 Chevrolet Impala 8.2 Chevrolet Malibu 6.8 Chrysler 300 9.3 Dodge Charger 9.3 Dodge Stratus 7.4 Ford Crown Victoria 9.3 Ford Focus 6.5 Honda Accord 6.6 Hyundai Elantra 6.7 Infiniti M35 9 Jaguar XJ8 8.6 Kia Amanti 9.3 Kia Spectra 6.5 Lexus GS300 7.4 Lexus LS 8.7 Lincoln Town Car 9.3 Mazda 3 6.5 Mercedes-Benz E 7 Mercury Grand Marquis 9.3 Nissan Altima 7.1 Pontiac G6 7.2 Saturn Ion 6.7 Toyota Avalon 7.2 Toyota Corolla 5.5 Volkswagon Passat 7.3 Volvo S80 8.2
