Question

As part of a study designed to compare hybrid and similarly
equipped conventional vehicles, *Consumer Reports* tested a
variety of classes of hybrid and all-gas model cars and sport
utility vehicles (SUVs) were tested. The following data show the
miles-per-gallon rating *Consumer Reports* obtained for two
hybrid small cars, two hybrid midsize cars, two hybrid small SUVs,
and two hybrid midsize SUVs; also shown are the miles per gallon
obtained for eight similarly equipped conventional models.

As part of a study designed to compare hybrid and similarly
equipped conventional vehicles, Consumer Reports tested a
variety of classes of hybrid and all-gas model cars and sport
utility vehicles (SUVs). The following data show the
miles-per-gallon rating Consumer Reports obtained for two
hybrid small cars, two hybrid midsize cars, two hybrid small SUVs,
and two hybrid midsize SUVs; also shown are the miles per gallon
obtained for eight similarly equipped conventional models.

An amusement park studied methods for decreasing the waiting
time (minutes) for rides by loading and unloading riders more
efficiently. Two alternative loading/unloading methods have been
proposed. To account for potential differences due to the type of
ride and the possible interaction between the method of loading and
unloading and the type of ride, a factorial experiment was
designed. Use the following data to test for any significant effect
due to the loading and unloading method, the type of ride,...
