The following table gives the daily income of 50 workers of a factory: Daily income (in Rs):  100-120  120-140  140-160  160-180  180-200 Number of workers:         12          14           8            6           10 Find the mean, mode and median of the above data.

The following table given the daily income of 50 workers of a factory : Find the mean of above data.

The following distribution gives the daily income of 50 workers of a factory: Daily income (in Rs): 100-120 120-140 140-160 160-180 180-200 Number of workers: 12 14 8 6 10 Convert the above distribution to a less than type cumulative frequency distribution and draw its ogive.

Consider the following distribution of daily wages of 50 workers of a factory. Daily wages (in Rs).: 100-120 120-140 140-160 160-180 180-200 Number of workers: 12 14 8 6 10 F i nd the mean daily wages of the workers of the factory by using an appropriate method.

The following distribution gives the daily income of 50 workers of a factory. {:("Daily income",,400-420,,420-440,,440-460,,460-480,,480-500),("Number of workers",,12,,14,,8,,6,,10):} Convert this distribution to less than type of cumulative frequency distribution and draw its ogive.
