Quizplus · Accepted Answer

The expected value for each characteristic is calculated by dividing the total number of observations by the number of characteristics. The total number of observations is $28 + 30 + 45 + 48 + 39 + 39 = 229$. There are 6 characteristics, so the expected value for each is $229 / 6 = 38.17$, which rounds to 38.
