Answer 1

The line plot is as follows:

1 3/4, 2 1/2, 3/4, 1 1/4, 2, 1 1/2, 2 3/4, 3 1/4, 1, 2 3/4

Part A: The greatest amount of rainfall is 3 1/4 inches and the least amount is 3/4 inches. The difference between them is 2 1/2 inches.

Part B: Out of the 10 months, 5 months had more than 2 inches of rainfall. So, the fraction of the 10 months with more than 2 inches of rainfall is 5/10.
