The federal guideline for smog is 12% pollutants per 10,000 volume of air. A metropolitan city is trying to bring its smog level into federal guidelines. The city comes up with a new policy where city employees are to use city transportation to and from work. A local governmental group does not think the city is doing enough and no real decrease will occur. An independent agency, hired by the city, runs its test and comes up with a P-value of 0.055. What is reasonable to conclude about the new strategy using a x=0.025?
A) There is a 94.5% chance of the new policy having no effect on smog.
B) There is a 5.5% chance of the new policy having no effect on smog.
C) There's only a 5.5% chance of seeing the new policy having no effect on smog in the results we observed from natural sampling variation. We conclude the new policy is more effective.
D) We can say there is a 5.5% chance of seeing the new policy having no effect on smog in the results we observed from natural sampling variation. There is no evidence the new policy is more effective, but we cannot conclude the policy has no effect on smog.
E) We can say there is a 5.5% chance of seeing the new policy having an effect on smog in the results we observed from natural sampling variation. We conclude the new policy is more effective.
