$30500 $41000 $35500
31500 39500 33500
30000 39000 35000
31000 38000 36500
31500 39500 36000

* Incorporate the 5-step hypothesis testing procedure
* If a significant F statistic is obtained, run a Post-Hoc Comparison's test on the 3
* Individual t-tests on all pairs of means can be done also
* Adjust level of significance to compensate for inflation
* Report which pairs of means are significantly different and their corresponding p
values if available
