In the digital age of marketing, special care must be taken to
make sure that programmatic ads appearing on websites align with a
company's strategy, culture and ethics. For example, in 2017,
Nordstrom, Amazon and Whole Foods each faced boycotts from social
media users when automated ads for these companies showed up on the
Breitbart website (ChiefMarketer.com). It is important for
marketing professionals to understand a company's values and
culture. The following data are from an experiment designed to
investigate the perception of corporate ethical values among
individuals specializing in marketing (higher scores indicate
higher ethical values).

Use 𝛼 = 0.05 to test for significant differences in
perception among the three groups.
State the null and alternative hypotheses.
H0: Not all the population means are
equal.
Ha: 𝜇MM = 𝜇MR = 𝜇AH0: 𝜇MM = 𝜇MR = 𝜇A
Ha: Not all the population means are
equal. H0: At least two
of the population means are equal.
Ha: At least two of the population means are
different.H0: 𝜇MM = 𝜇MR = 𝜇A
Ha: 𝜇MM ≠ 𝜇MR ≠ 𝜇AH0: 𝜇MM ≠ 𝜇MR ≠ 𝜇A
Ha: 𝜇MM = 𝜇MR = 𝜇A

Reject H0. There is sufficient evidence
to conclude that the mean perception score is not the same for the
three groups of specialists.
Do not reject H0. There is sufficient

At the 𝛼 = 0.05 level of significance, we can conclude
that there are differences in the perceptions for marketing
managers, marketing research specialists, and advertising
specialists. Use the procedures in Section 13.3 to determine where
the differences occur. Use 𝛼 = 0.05. (Use the
Bonferroni adjustment.)
Find the value of LSD. (Round your comparisonwise error rate to
four decimal places. Round your answer to three decimal
places.)
LSD =
Find the pairwise absolute difference between sample means for
each pair of treatments.
