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 -value is - Select your answer -less than .01between .01 and .025between .025 and .05between .05 and .10greater than .10Item 6

What is your conclusion?

- Select your answer -Cannot conclude there are differences among the mean perception scores for the three groupsConclude the mean perception scores for the three groups are not all the sameItem 7
