Solar Panels For Homes

Research question: Is the mean solar cell output the same for all cell types? (please see details)?

Mean output of solar cells of three types are measured six times under random light intensity over a period of 5 minutes, yielding the results shown.

mean is the sum of all values of each test divided by the number of tests
therefore A:(123 + 121 + 123 + 124+ 125+127) / 6 = 128 5/6
Same calc for B: Ans is : 123
C ans= 127 5/6
Therefore the mean of each test is not the same
