What is the mean yield across the four quarters for the dataset [120, 150, 130, 170]?

Explanation:
The mean yield is found by adding all quarterly yields and dividing by the number of quarters. Add them: 120 + 150 + 130 + 170 = 570. There are four quarters, so 570 divided by 4 equals 142.5. This value represents the average yield per quarter over the year. It lies between the middle values and is slightly pulled up by the higher quarters (150 and 170) compared to the lower ones (120 and 130). The other options correspond to individual quarter values, not the overall average across all four quarters.
