Q.3

k = 24% of X
n° of households with 4 TV = 20% of X

Thus, in terms of k, n*of households with 4 TV comes from \(k = 0.24X\), then \(X= \frac{k}{0.24}\).

Substituting X into the second statement, we get \(0.2*\frac{k}{0.24}=\frac{5}{6}k\)

For the first question is the middle number of the five. Which is 3

For the second one you cannot determine the average because you do have 5 or more numbers which could be also one million.

Hope is more clear now.

Ask if you do need.

In question 1, "What is the median number of televisions per household"
isn't the table mean that the total number of TVs depends on the number of households?

To clarify, if we assume the total households is 100
then we have sixteen Zero, eight 1s..

if we assume the total households is 200
then we have 32 zero ?

other thing, if I assumed the above understanding is wrong .. why the answer is 3 not 2.5 ?
