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
0.025

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?

What are the hypotheses for this​ test?







A.



H0​:

At least one of the means is different from the others.


H1​:

μ1=μ2=μ3







B.



H0​:

μ1=μ2=μ3



H1​:

At least one of the means is different from the others.






C.



H0​:

μ1≠μ2≠μ3



H1​:

μ1=μ2=μ3







D.



H0​:

μ1=μ2=μ3



H1​:

μ1≠μ2≠μ3






Determine the test statistic.



F=nothing

​(Round to two decimal places as​ needed.)

Identify the​ P-value.



​P-value=nothing

​(Round to two decimal places as​ needed.)

What is the conclusion of the​ test?








Reject

Do not reject




the null hypothesis. Conclude that the type of vehicle





does not

does
