a. Compute the values identified below (to 1 decimal, if necessary).

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 Selectl {less than .01,between .01 and .025, between .025 and .05, between .05 and .10,greater than .10}

What is your conclusion?
Select {Conclude the mean perception scores for the three groups are not all the same, Cannot conclude there are differences among the mean perception scores for the three groups}Item7

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 for marketing managers (1), marketing research specialists (2), and advertising specialists (3).
