Does having many internet tabs open affect the completion of a task? Researchers gathered a random sample of college students.

Tab count: the number of tabs the student had open while completing the task
Tab usage status: student opened many different internet tabs simultaneously ("tab collector") or student used at most two tabs at a time ("streamlined searcher")

Describe how nonresponse might lead to bias in this survey. Does the stated margin of error account for this possible bias?
People who have longer travel times to work might have less time to respond to a survey. This would cause our estimate from the sample to be greater than the true mean travel time to work. The bias due to nonresponse is not accounted for by the margin of error.

The bias due to nonresponse is accounted for by the margin of error.

As the randomly selected telephone numbers are called repeatedly till answer is received, the chance of selection bias is reduced.
However, due to telephone survey, the section of the population without telephones cannot be reached, introducing selection bias from a different angle.
Moreover, if the survey is carried out within a short time of the year and not over the whole year, it might over-represent the opinions of individuals born at a certain time of the year, while under-representing those born at other times. This again leads to selection bias.
It is also known that people may not always respond truthfully, thus leading to nonresponse bias

An automotive service center would like feedback on its customer service. Each customer receives a printed card after they pay for services with a short survey on which customer service is ranked on a scale from 1 (least satisfied) to 5 (most satisfied). Customers can then choose to submit the card in a box on their way out of the store. The store manager finds that 140 cards were filled out in the past week, with an average customer satisfaction score of 2.47. Which type of bias is most likely to be present in the survey results?
A. This is undercoverage bias because some types of customers may not have received cards.
B.This is nonresponse bias because many customers may choose to not fill out the cards.
D.This is question wording bias because the customer service score levels may not be clear to customers.
C. This is response bias because customers may not be truthful about their experience with customer service. hp
