Step-by-step explanation:
The range is 21 and mean is 29.17.
Step-by-step explanation:
The data set is:
S = {31, 37, 35, 38, 32, 23, 17, 18, 35, 20, 35, 29}
The range is the difference between the maximum and minimum value.
Maximum = 38
Minimum = 17
Range = Maximum - Minimum
= 38 - 17
= 21
Compute the mean as follows:
(31+37+35+38+32+23+17+18+35+20+35+29)
=29.17
Thus, the range is 21 and mean is 29.17.

STEP BY STEP EXPLANATION :
TO FIND THE MEAN :
MEAN : ADD ALL NUMBER / TOTAL VALUE GIVEN
MEAN : 31+37+35+38+42+23+17+18+35+25+35+29 /12
MEAN = 365/12
MEAN = 30.41
TO FIND THE RANGE :
RANGE : HIGHEST MARKS - LOWEST MARKS
RANGE : 42-17
RANGE = 25
RESULT : HENCE , THE RANGE OF THE GIVEN DATA IS 25 AND THE MEAN IS 30.41
