Question

Ages of players in a cricket team are 25,26,25,27,28,30,31,27,33,27,29.
[1]find the mean and mode of the data[2]find the minimum of 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

mean = sum of observations/

Total no of observations

hence, mean = 25+26+25+27+28+30+31+27+33+27+29/11

= 308/11

= 28

hence , mean = 28.........

now

median = for odd no.

n+1/2

so, 11 = n .. where n= odd no.

11+1/2

= 12/2

= 6

hence median= 6......

hopefully it will work
