Answer 1

hye

=============================

for finding the cumulative freiquency 

step 1 : find the relative frequency

step 2 :now ,  divide the frequency by the total number of data values.

step 3 :now , add all of the previous relative frequencies to the relative frequency for the current row.

step 4:then u find the cumulative friquency
