Answer:
q = 80
Step-by-step explanation:
Here, we want to get the value of w
Mathematically, we can obtain the cumulative frequency from the frequency tab
To do this, we have to sum up the frequencies at each point to get the cumulative at each point
We add the frequency above to the frequency below to get the value of the cumulative frequency at that point
We have it that;
we start with 10: as seen on the frequency column
then we proceed;
10 + 20 = 30
30 + 30 = 60
60 + 20 = 80
80 + 10 = 90
90 + 10 = 100
As we can see here, the value of q is 80
