Use = .05 to test for a significant difference in perception among the three groups.
1. Calculate the value of the test statistic (to 2 decimals).
2. The p-value is:. a. less than .01b. between .01 and .025c. between .025 and .05d. between .05 and .10e. greater than .103. What is your conclusion?
a. Conclude the mean perception scores for the three groups are not all the sameb. Cannot conclude there are differences among the mean perception scores for the three groupsItem 7
4. Using = .05, determine where differences between the mean perception scores occur.
