Answer: a) undercoverage.

Step-by-step explanation:

  • <u>Undercoverage</u>: It is a kind of selection bias. When some data is represented inaccurately in a survey, then we call it suffer from undercoverage.
  • <u>False response</u>: It means the survey shows false results.
  • <u>Non response</u>: It means the survey shows no response.

Here, 4% of households have no telephone, 10% have only cell phones, and another 25% have unlisted telephone numbers.

It shows that data inadequately represented in the sample.

Thus, the sample will suffer from<u> undercoverage</u>.

Correct option: a) undercoverage.

Morgarella [4.7K]
A. y - 1 = 3x + 6
Add 1
y = 3x + 7

Subtract 6, then divide by 3
3y = x - 7
y = 1/3x - 7/3

C. y - 2 = 1/3x + 1
Add 2
y = 1/3x + 3

D. y + 1 = 3x - 6
Subtract 1
y = 3x - 7
