Calculate the test statistic. (Round your answer to two decimal places.)
F = 1.84
Use technology or SALT to find the P-value. (Round your answer to four decimal places.)
P-value = 0.1806
What can
conclude?
O Fail to reject Ho. There is convincing evidence that the average number of miles until failure is not the same for all four brands of spark plugs.
O Reject H,. There is not convincing evidence that the average number of miles until failure is not the same for all four brands of spark plugs.
O Fail to reject Ho. There is not convincing evidence that the average number of miles until failure is not the same for all four brands of spark plugs.
O Reject H.. There is convincing evidence that the average number of miles until failure is not the same for all four brands of spark plugs.
