A mobile phone service provider wants to survey its customers to study privacy concerns and the sharing of their personal Information. They call 5000 randomly selected phone numbers from a database containing the phone number of every customer. If someone selected doesn't answer,
they'll attempt calling back up to 2 more times before giving up on reaching that person.
They reach 350 customers with this strategy, and 60% of those reached say they are at least somewhat concerned about their personal
information being shared without their knowledge or consent.
Which of those is the most concerning potential source of bias in the provider's survey?
A Bias from undercoverage
B Bias from using voluntary response
C Response bias
D Nonresponse bias

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

ok so the answer to your question is simple as long as you look at the different dimensions that contain the exemplary letters that combined in the right order give you words that eventually within the 5th dimension will conform and give you the correct answer to your question. hope i , stop looking at this easily, look at it with a spectral view.
