Question

Que > The marks in a subject for 12 students are
as follow :
31,37,35,38,42, 23, 17, 18,35,25,35,29
For the given data, find the Range & Mean ​

Answer 1

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.

Answer 2

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
