Answer: C. 18
Step-by-step explanation:
We know that the range of a data set is the difference between the maximum data value and the minimum data value.
Given : The numbers of days of rain per month in Seattle, for a period of twelve months, are:
18, 14, 16, 14, 12, 9, 5, 0, 7, 13, 18, 17
Maximum data value = 18
Minimum data value = 0
Then , the range of the data set will be :-
Range = 18-0 =18
Hence, the range of the data values =18
