He was considering altering die layout of the store so that the frozen food section would be near the section with fresh fruit and vegetables. These changes were designed to better accommodate customer shopping patterns and thereby increase customer patronage. Prior to making the alterations, he decided to administer a short questionnaire in the store to a random sample of customers.

Hoffman gave specific instructions that on no account were customers to be harassed or offended. Identify the major sources of noncoverage and nonresponse errors. Explain.
