Determine whether each sample may be biased. Explain.
5. Rickie surveys people at an amusement park to find out the average size of people's immediate family

6. Theo surveys every fourth person entering a grocery store to find out the average number of pets in people's homes.

7. A biologist estimates that there are 1,800 fish in a quarry. To test this estimate, a student caught 150 fish from the quarry, tagged them, and released them. A few days later, the student caught 50 fish and noted that 4 were tagged. Determine whether the biologist's estimate is likely to be accurate.

NO FILES OR I REPORT grr >:-(

Answer: Hope this may help.

5 biased

6 biased

7 unbiased, accurate

Step-by-step explanation:

5 is biased as not all family's may be or even go to the amusement park.

6 is biased, every fourth person entering is fair, however not everyone with pets at home are going to the grocery store.

7 is accurate and not biased as it does not specifically say one fish kind, and it is pretty fair.

(This is what I think but it may be wrong)
