(a) Make stemplots to investigate the shapes of the distributions. The brain
activities for both box-office hits and failures are skewed to the right and
the brain activity for box-office failures has a high outlier. Researchers were
uncertain whether this movie should have been classified as a box-office
failure, and because of this uncertainty, we believe there is some justifica-
tion for removing the outlier.
0) We suspect that brain activity for box-office hits is larger than that for box-
office failures. Do the data (with the outlier removed) support this suspicion

failures?" Seven subjects viewed movie trailers for eventual box-office hits (ho
office revenues of more than $80 million) and their brain activity was measSUral
using electroencephalography (EEG). Similarly, 11 subjects viewed movie
trailers for eventual box-office failures (box-office revenues of less than $20
million) and their brain activity was also measured. Brain activity was reported
as a standardized score. Here are the standardized scores:
