The mean is calculated by finding the sum of all the values in the set and then dividing by the total number of values. In this case, for the given set, the sum is 23 and the total number of values is 4. Therefore, the mean is 5.75. However, none of the given choices match this value exactly. Option A is incorrect because the mean is not 5 but 5.75. Option C is incorrect because the mean is not 7 but 5.75. Option D is incorrect because the mean is not 8 but 5.75. Therefore, option B, with a value closest to the mean, 6, is the correct answer.
