Question 3
Using the data set below, determine if
there is a difference in the method of advertisement strategies
employed via sample products in (1) all color, (2) all
black-and-white, and (3) a combination of both. Utilize the
appropriate statistical test to examine if the three formats differ
in attactiveness, and explain the results you achieve as to whether
or not this is the case.
