Answer: B) 11c to 31c
Explanation:
We know that the range of any data gives us a interval which contains all the data and provides an indication of statistical dispersion from minimum value to the maximum value.
The given set of measurements : - 27c, 12c, 31c, 19c, 23c, 11c, 17c
Here the highest measurement :- 31c
The least measurement :- 11c
Then , the range of the given set will be :-
11c to 31c
Hence, the range for the given set of measurements is 11c to 31c .
