Respuesta :

Answer:

The rate of non response for this sample is 89.05%.

Step-by-step explanation:

Total number of listed residential telephone numbers in the United States = 45,956

Number of telephone numbers on which call completed = 5029

So, the number of calls not completed = [tex]45956-5029=40927[/tex]

The rate of non response for this sample is = [tex]\frac{40927}{45956}[/tex]

= 0.8905

And in percentage it is 89.05%.
