The data found below measure the amounts of greenhouse gas emissions from three types of vehicles. the measurements are in tons per year, expressed as co2 equivalents. use a 0.05 significance level to test the claim that the different types of vehicle have the same mean amount of greenhouse gas emissions. based on the results, does the type of vehicle appear to affect the amount of greenhouse gas emissions?

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
