Extracted text: 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). 13 The p-value is less than .01 What is your conclusion? Conclude the mean perception scores for the three groups are not all the same c. Using a = .05, determine where differences between the mean perception scores occur.
