Question

Suppose a local newspaper wishes to survey the voters of a city to project the results of the upcoming election for city mayor. The newspaper hires a team of statisticians who will randomly select 500 phone numbers from the city’s voter registration records to call between the hours of 8am and 4pm.

Which of these is an issue regarding the generalizability of the results?

Answer 1

Answer:

See below

Step-by-step explanation:

The condition that calls be made between 8am and 4pm will exclude anyone who leaves home for work or school during those hours, which are the most common work periods of the day.  The sampling will consist primarily of home-keepers, babysitters, or students skipping class or doing homework, with an occasional worker who works the night shift and is upset with the call since it woke that person from sleep.
