Mean of the data =35 hours 
Median=31.2 hours 
Sample size=24 families 
We have said that 24 of the sample families watched television for no more than 20 hours each week.
The 6th percentile of the data is 20 hours, and we have provided that.
We must determine how many families make up the sample.
Assume there are N families.
We have said that 24 of the sample families watched television for no more than 20 hours each week.
So, 6% of N=24 
6100×N=24 
N=400 families
