Answer:

The correct answer is option d

Step-by-step explanation:

It is given that two months ago, the average daily rainfall in a certain city was 9.4 cm, with a mean absolute deviation of 3.5 cm. Last month, the average daily rainfall in city rose to 11.5 cm, while the mean absolute deviation dropped to 1.6 cm.

Since the mean absolute deviation indicates variation, it is clear that last month experienced less variability than the previous month.

Thus, option d) indicates that the daily rainfall for last month had less variation compared to the month before.
