In a bumper test, three types of sub-compact cars were deliberately crashed into a barrier at 5 mph with the resulting damage (in dollars) recorded. Eight test cars of each type were crashed. Test results indicated that post-hoc procedures were warranted. The TUKEY HSD approach was used with the following results:

Using an overall significance level of 5%, is there evidence that one type of car had less bumper damage than the others? Which car appears to have the least bumper damage?

▸ Yes, the confidence interval results show that Car 1 has less damage than 2 or 3.

▸ No, there is not enough evidence to say that one type of car has less damage than the others because the intervals all overlap.

▸ Yes, the confidence interval results show that Car 2 has less damage than 1 or 3.

▸ Yes, the confidence interval results show that Car 3 has less damage than 1 or 2.
