Four different types of solar energy collectors were tested. Each was tested at five randomly chosen times, and the power (in watts) was measured. The results were as follows.CollectorPowerA1.91.62.01.81.6B1.71.91.81.71.7C1.20.91.20.91.4D1.51.01.41.31.4(a) Using  = 0.05, can you conclude that the mean power differs for different collectors?
