If mode $= 25$ and mean $= 19,$ then median $= \dots$

The following table shows the cumulative frequency distribution of marks of $800$ students in an examination:

Marks	Number of students
Below $10$	$10$
Below $20$	$50$
Below $30$	$130$
Below $40$	$270$
Below $50$	$440$
Below $60$	$570$
Below $70$	$670$
Below $80$	$740$
Below $90$	$780$
Below $100$	$800$

Construct a frequency distribution table for the data above.

For some given data,if $Z = 95$ and $\bar{x} = 98,$ then $M = \ldots \ldots \ldots$

$\frac{Z-M}{M-\bar{x}}=\ldots \ldots \ldots \ldots$

If $M = 72$ and $\bar{x} = 70$,then $Z = \ldots \ldots \ldots \ldots$

In the usual notations,$Z - M = \ldots \ldots \ldots \quad (M - \bar{x})$
