In this case, we have that there is a relationship between width and height, which is 16: 9, which means that any screen that has the same ratio would be an identical screen.

How would we do this? it must either be raised to a power or rationalized on both sides of the ratio.

If we raise to a power, it would give very large dimensions for an HDTV, therefore, it is best to remove the square root on both sides, since it has more common values for a TV.

$\sqrt{16} :\sqrt{9}$

4: 3

Therefore, a 4: 3 screen is a good choice for an HDTV with the same ratio.

lawyer [7]

Answer:

Step-by-step explanation:

Given that the hartford insurance company has hired you to poll a sample of adults about their car purchases.

Here the insurance company is using convenience sampling to select customers so they resorted to taking the names from telephone directories.

But this may not be reliable since persons owning cars need not have telephones and similarly persons having telephones need not own cars

Owning a car and name appearing in telephone directory need not be associated at all

So taking random sample of names from telephone directories may not give the required accurate result since here sample cannot be assumed to represent the population of car owners.
