Answer:
1.244"
Step-by-step explanation:
The mean is given by dividing the sum of the given numbers by the frequency. In this case, the frequency is 5 since we're given 5 rainfall data. The sum of the respective rainfall is equivalent to 1.7"+2.2"+0.5"+0.72"+1.1"=6.22"
Now dividing the above sum by frequency yields mean as follows
[tex]Mean=\frac {6.22}{5}=1.244"[/tex]
