Answer 1

Range is the difference between the highest and lowest numbers.
18-0 = 18

Answer 2

Answer: C. 18

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
