Explanation of Solution

Given information: Consider the question given to find out the number of American household who watched a certain program when in a survey, out of $5000$ American households, $460$ households watched that program.

Calculation:

Total numbers of American households are about $105\text{ million}$ . To find out the number of households that watched the program, follow the steps given below:

Total number of households of the sample= $5000$

Number of households that watched the program= $460$

Evaluate the percentage of households that watched the program. Therefore,

  $\frac{460}{5000}=0.092=9.2\%$

Hence, the percentage of households that watched the program is $9.2\%$ .

Find $9.2\%$ of the total number of households in America.

  $9.2\%·\text{ 105 million households = 9}\text{.66 million households}$

Hence, about $\text{9}\text{.66 million}$ American households watched the program.
