[Question]
Identify what, if any, bias is found in each of the following sampling
scenarios.
Explain your answer for each one.
a) Selecting some residents of a building to participate in a survey
of recycling options based on the last digit of their phone number
b)Deciding whether to create a new restaurant menu based on the
responses of customers who returned a survey card
c) Polling members of a business association to gauge public reaction
to a proposed new business tax
[Difficulty]
There's a blur between sampling bias, response bias and household
bias...I don't know which is applicable, but was wondering if I could
get a second opinion for my attempt

Identify what, if any, bias is found in each of the following sampling
scenarios.
Explain your answer for each one.
a) Selecting some residents of a building to participate in a survey
of recycling options based on the last digit of their phone
number-This is an example of sampling bias as the last digit of the
phone number may not be a good sampling criterion as there may only be
five residents who have that digit, and there may be 200 different
residents
b) Deciding whether to create a new restaurant menu based on the
responses of customers who returned a survey card-This is an example
non-response bias, as the statement implies that there were people
that did not return a survey card, as is usually the case with surveys
that are taken home
c) Polling members of a business association to gauge public reaction
to a proposed new business tax-This is household bias as only polling
members of a business association will exclude those who are not
members of the association or do not own a business
