A research firm is conducting a study to estimate the average daily television viewing time for adults in a particular state. They decide to use a telephone survey, calling 500 randomly selected landline numbers between 9:00 AM and 5:00 PM on weekdays. The survey finds an average of 4.2 hours of TV viewing per day. Which of the following statements is the most accurate assessment of this sampling method?
The sampling method is likely to produce an unbiased estimate because 500 landline numbers were randomly selected.
The estimate is likely an underestimate because many people are at work during the day.
The sampling method is flawed because it excludes individuals who only have cell phones and may overrepresent certain demographics.
The sample size is too small to make a reliable estimate for an entire state.
