Cormpute the values identified below (ta 2 decimal, if necessary) Sum of Squares, Treatment Sum of Squares, Error Mean Squares, Treatment Mean Squares, Error b. Use -.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 1 -select your answer . what is your condlusion? C. Using = .05, determine where differences between the mean perception scores occur. Calculate Fisher's LSD value (to 2 decimals). Test whether there is a significant difference between the means far marketing managers() marketing research specialists (2), and advertising specialists (3).

SSA=6(7-8.83)^2+6(9.5-8.83)^2+6(10-8.83)^2=31
SSW=(8-7)^2+……..+(10-10)^2=7.5
MSA=31/(3-1)=15.5
MSW=7.5/(18-3)=0.5
F=MSA/MSW=15.5/0.5=31
Fcrit=3.68
Since F>Fcrit, reject the null hypothesis. Thus, we conclude that there is difference in the perception.
