Ages of players in a cricket team are 25, 26, 25, 27, 28, 30, 31, 27, 33, 27, 29.

(i) Find the mean and mode of the data. 

(ii) Find the minimum number of players to be added to the above team so that mode of the data changes and what must be their ages.

Answer 1

i) Given that the ages of players of a cricket team are 25, 26. 25. 27. 28. 30, 3i. 27. 33, 27, 29

Mean = \(\frac {Sum\,of\,the\,ages}{Number\,of\,players}\) 

= 28

Mode = frequently appeared = 27 

ii) To change the mode minimum two players of age 25 must be added.
