Answer 1

On average, Albani gets 20.933 inches of rain per year.

On average, Zachary gets 24.734 inches of rain per year.

On average, Zachary gets more rain than Albani.

Explanation:

Mean is given by:

`Mean = (Sum)/(Total)`

For Albani :

Sum of total number of terms = 23.36+18.51+28.54+22.36+30.50+24.74+11.93+15.34+18.07+15.98

Sum of total number of terms = 209.33

Number of terms = 10

`Mean=(209.33)/(10)\\\\Mean=20.933\\`

For Zachary :

Sum of total number of terms = 27.27+20.11+31.14+25.88+32.97+25.03+18.55+23.91+22.75+19.73

Sum of total number of terms = 247.34

Number of terms = 10

`Mean=(247.34)/(10)\\Mean=24.734`
