What is the decision and conclusion at the 0.01 level of significance?

A. Reject the null hypothesis

We have sufficient evidence to conclude that the means in these three samples are not the same with 99% confidence.

B. Reject the null hypothesis

We have sufficient evidence to conclude that the population mean MPG are not the same for at least two of the three groups of numbers of cylinders.

C. Fail to Reject the null hypothesis

We do not have sufficient evidence to conclude that the population mean MPG are not the same for the three groups of numbers of cylinders.

D. Reject the null hypothesis

With a 1% chance of committing a type 1 error, we will conclude that the three sample mean miles per gallon for the three groups represented by 4, 6, and 8 cylinder cars, at least two are not equal.
