Use -.05 to test for a significant difference in perception among the three groups. Calculate the value of the test statistic (to 2 decimals). 7.5 .5 36.98 The p-value is less than-01 What is your conclusion? Conclude the mean perception scores for the three groups are not all the ssme c. Using a.05, determine where differences between the mean perception scores occur.
