Question

The telephone company made this table to show the number of telephones in the homes they surveyed:

Phones in home 0 1 2 3 4 or more
Number of homes 7 33 56 42 12
If these homes are representative of the community of 100,000 homes that the company serves, about how many homes would you predict have 4 or more telephones?

A) 12,000
B) 6,000
C) 24,000
D) 10,000
E) 20,000"

Answer 1

To predict the number of homes with 4 or more telephones in a community of 100,000 homes, we can use the given table as a representative sample.

Step-by-step explanation:

To predict the number of homes that have 4 or more telephones, we can use the given table as a representative sample of the community. We can calculate the percentage of homes with 4 or more telephones and then apply that percentage to the total number of homes in the community.

Using the table, we can see that there are 12 homes with 4 or more telephones. The total number of homes in the sample is 7 + 33 + 56 + 42 + 12 = 150. So, the percentage of homes with 4 or more telephones is 12/150 = 0.08.

Now, we can apply this percentage to the total number of homes in the community, which is 100,000. So, the number of homes with 4 or more telephones would be 0.08 * 100,000 = 8,000.
