4. Is fishing better from a boat or
from the shore? Pyramid Lake is located on the Paiute Indian
Reservation in Nevada. Presidents, movie stars, and people who just
want to catch fish go to Pyramid Lake for really large cutthroat
trout. Let row A represent hours per fish caught
fishing from the shore, and let row B represent
hours per fish caught using a boat. The following data are paired
by month from October through April.

Use a 5% level of significance to test if there is a difference
in the population mean hours per fish caught using a boat compared
with fishing from the shore.
