The median of 19 observations is 30. Two more observation are made and the values of these are 8 and 32. Find the median of the 21 observations taken together.
Hint Since 8 is less than 30 and 32 is more than 30, so the value of median (middle value) remains unchanged.
उत्तर
Since, 8 is less than 30 and 32 is more than 30, so the middle value remains unchanged
Thus, the median of 21 observations taken together is 30.
