I need help with this, please

Answer 1

Given:

Given that the pie chart shows the relative frequency distribution resulting from a survey of 6000 US rural households with internet connections in a certain year.

We need to determine the total number of households with each type of internet in the survey.

Cable modem:

Since, the relative frequency distribution for cable modem is 0.142

The total number of households that use cable modem is given by

$0.142 \times 6000=852$

Thus, 852 households use cable modem.

DSL:

Since, the relative frequency distribution for DSL is 0.092

The total number of households that use DSL is given by

$0.092 \times 6000=552$

Thus, 552 households use DSL.

Dialup:

Since, the relative frequency distribution for dialup is 0.747

The total number of households that use dialup is given by

$0.747 \times 6000=4482$

Thus, 4482 households use dialup.

Others:

Since, the relative frequency distribution for others is 0.019

The total number of households that use others is given by

$0.019 \times 6000=114$

Thus, 114 households use others.
