The following data are from an experiment designed to investigate the perception of corporate ethical values among individuals who are in marketing. Three groups are considered: management, research and advertising (higher scores indicate higher ethical values). Marketing Managers Marketing Research Advertising a. Compute the values identified below (to 1 decimal, if necessary). Sum of Squares, Treatment Sum of Squares, Error Mean Squares, Treatment Mean Squares, Error b. Use a = .05 to test for a significant difference in perception among the three groups. Calculate the value of the test statistic (to 2 decimals). The p-value is Select What is your conclusion? Select

Thank You!

SST=7.00

SSE=7.5

MST=3.5

MSE=0.5

b) F stat= 7.00

P value=0.007

Since P value is SMALLER than the level of significance 0.05 therefore REJECT H0. We have sufficient evidence to conclude that there is difference in means.

c) LSD = 2.13 √ (0.5 * (2/6))= 0.87

SIGNIFICANT

x1 - x2 = -1.50

SIGNIFICANT

.c1 - 83 = -1.00

NOT SIGNIFICANT

r2 - 73 = 0,50
