and 4 th number is 17 ..

so the median is 17

Answer 2

SOLUTION

TO DETERMINE

The median of the calls received on 7 consecutive days 11, 13, 17, 13, 23, 25, 19.

CONCEPT TO BE IMPLEMENTED

Median

Median is the middle most value of a set of observations when the samples are arranged in order of magnitudes ( Either in ascending or in descending)

EVALUATION

Here the given observations are

11, 13, 17, 13, 23, 25, 19

Rearranging in ascending order we get

11 , 13 , 13 , 17 , 19 , 23 , 25

Total number of observations = 7 which is odd

Hence the required median

= The middle most value of a set of observation

= 4 th observation

= 17

Hence the required median = 17
