If the median of the distribution given below is 28.5 , find the values of x and y. |
Answer» Solution : Since the total number of observation is 60 `:. 45+x+y=60rArr x+y=15` Median is GIVEN to be 28.5 so it will fall in the class 20-30 `:. """Median"=l_(1)+(((N)/(2)-C))/(f)xxi` `rArr 28.5=20+(30-(5+x))/(20)xx10` `rArr 57-4025-x` `rArr x=8` Putting the VALUE of x=8 in eq. (1) we get Hence, x=8,y=7 |
