Two random samples were taken to determine how often people in a community listen to the local radio station each month.
the first sample surveyed 15 people as they exited the bank on main street. the first sample found that the mean number of hours they listened to the radio each month was 20.
the second sample surveyed every sixth person as they exited the only local grocery store until 100 people were surveyed. the second sample found that the mean number of hours they listened to the radio each month was 12.

It is a random sample

The second sample is more representative of a population

The second sample gives better representation because it is larger

Step-by-step explanation:

According to the given statement we have been given two statements and we have to determine  how often people in a community listen to the local radio station each month.

If you notice the second sample it is a random sample because people who visited the store had equal probability of being chosen.

The second sample is more representative of a population because it is a larger sample than the first sample and the sample are taken from the only local grocery store.

The second sample gives better representation because it is larger ...

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
