1.3: Simple Random Sampling 1. Suppose a veterinary inspector needs to inspect the animals at a local zoo to determine whether they are healthy and being well-cared for. The table shows the animals and their respective groups. Mammals Birds 1. Aardvark 6. Lion 11. Flamingo 16. Hawk 2. Buffalo 7. Zebra 12. Swan 17. Owl 3. Elephant 8. Pig 13. Sparrow 18. Chicken 4. Squirrel 9. Dog 14. Parrot 19. Duck 5. Rabbit 10. Horse 15. Pelican 20. Turkey Reptiles Fish 21. Gecko 26. Python 31. Catfish 36. Shark 22. Iguana 27. Turtle 32. Tuna 37. Trout 23. Chameleon 28. Tortoise 33. Cod 38. Perch 24. Rattlesnake 29. Alligator 34. Salmon 39. Guppy 25. Boa constrictor 30. Crocodile 35. Goldfish 40. Minnow a. Using your calculator, find a simple random sample of 8 animals. (State your calculator entry and the results). b. Suppose the reptile enclosure is the first thing the vet sees when she walks into the zoo and so she decides to just get all 8 animals from that area. What kind of sample is this? Convenience c. Suppose a SRS of the animals yields: 12, 31, 33, 20, 28, 16, 37 and 40. Explain why, even though this was a SRS, it would not be a good sample. d. Explain how the vet could take a good sample of size 8 that fairly represented all 4 groups of animals and was not biased
