Question

Listed below are measured amounts of greenhouse gas emissionsfrom cars in three different categories. The measurements are intons per year, expressed as CO2 equivalents. Use a 0.05 level ofsignificance to test the claim that the different car categorieshave the same mean amount of greenhouse gas emissions. Based on theresults, does the number of cylinders appear to affect the amountof greenhouse gas emissions?

Four cylinder   7.2    7.9   6.8   7.4    6.5    6.6   6.7    6.5    6.5   7.1   6.7    5.5   7.3

Sixcylinder      8.7     7.7    7.7    8.7   8.2    9.0    9.3  7.4    7.0   7.2     7.2    8.2

Eightcylinder     9.3   9.3    9.3    8.6     8.7    9.3     9.3

The answer is below please help withthe solution

Test stat F=32.3210, CV F = 3.3277.P 0.0000. Reject the hypothesis thatthe means are equal. More cylinders means morenasty.
