Brent Perry works as a guide and conservationist for an ornithological tourism company, which is part of an emerging industry catering to birders. He recently surveyed the bird populations in some preserved deciduous woodlands in Northern New Jersey. In particular, he was looking for Baltimore Orioles who surprisingly to some have taken up residence in Jersey elms and maples. On five random visits each along five separate and independent mile-long pathways (Trails A through E), he recorded the following numbers of sightings of Baltimore Orioles:
|
Trail A |
8 |
16 |
8 |
12 |
16 |

Trail B |

15 |

Trail C |

Trail E |

He kept other variables about his bird watching as constant as he reasonably could. He wonders if all five pathways provide comparable opportunities to spot these orange-plumed birds. Help Brent with his analysis by completing the following organizer after performing the relevant testing at the 0.5% level of significance. Round off any decimals to five decimal places if necessary.
