Answer 2

Answer:

Option B) The annual rainfall in Falls City is generally more than of the annual rainfall in Rockaway Beach.        

Step-by-step explanation:

We are given the following information:

The mean annual rainfall in Rockaway Beach = 118.88 inches

The mean annual rainfall in Falls City = 122.28 inches

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

Mean annual rainfall in Falls City  > Mean annual rainfall in Rockaway Beach

From this information we can conclude:
