Question
Microhabitat factors associated with forage and bed sites of barking deer in Hainan Island, China were
examined from 2001 to 2002. In this region, woods make up 4.8% of the land, cultivated grass plot makes up
14.7%, and deciduous forests makes up 39.6%. Of the 426 sites where the deer forage, 4 were categorized as
woods, 16 as cultivated grassplot, and 61 as deciduous forests. The table below summarizes these data.

a) Write the hypotheses for testing if barking deer prefer to forage in certain habitats over others.
Ho: All habitats are equally prefered vs HA: Cultivated grassplot habitats are prefered over others
Ho: All habitats are equally prefered vs HA: Wood habitats are prefered over others
Họ : All habitats are equally prefered vs HA: Some habitats are prefered over others
Ho: All habitats are equally prefered vs HA: Deciduous habitats are prefered over others
b) What type of test can we use to answer this research question?
O Chi-square
Hypothesis test of means
Hypothesis test of proportions
c) Do these data provide convincing evidence that barking deer prefer to forage in certain habitats over
others? Conduct an appropriate hypothesis test to answer this research question. Round your test statistic to 3
decimal places.
