a) The mean (average of all the values) is (203 / 10) = 20.3 million dollars.
b) The median (as there are even number of values, take average of the middle two values when sorted) is (15.4 + 12.9) / 2 = 14.15 million dollars.
c) As no value is repeating, there is no mode for this dataset.
d) The midrange (the average of the highest and lowest salaries) is (38.4 + 7.7) / 2 = 23.05 million dollars.
As these are the top 10 values, they do not give any information about the salaries of TV personalities in general. So, the correct answer is (D).
The top 10 salaries give us an estimate of how much a top TV personality would earn. However, as these are few in number, this does not help us much in general.
