We have reason to believe that more Mourning Doves habitat the Catalina Mountains versus the University of Arizona campus. ? This can be concluded since our PValue is smaller than our significance level of . ????????????212111)?1(?)??(nnppppznxpi ??2121?nnxxp??? ?????? ????10011001)()(zResults from Ztest Bird Species Null/Alternate Hypothesis Z Value P Value Conclusion Mourning Dove Ho : p1 = p2 Ha : p1 p2 Reject Null Hypothesis Cactus Wren Ho : p1 = p2 Ha : p1 p2 Reject Null Hypothesis Quail Ho : p1 = p2 Ha : p1 p2 Reject Null Hypothesis Road Runner Ho : p1 = p2 Ha : p1 p2 Fail to Reject Null Hypothesis Sparrow Ho : p1 = p2 Ha : p1 p2 Reject Null Hypothesis Pigeon Ho : p1 = p2 Ha : p1 p2 Reject Null Hypothesis Calculations: Using Shannon Diversity Index *The Shannon Diversity Index is used to pare species diversity between study sites. Shannon Diversity Index equations used: H1= (nlogn ∑ f1log f1) / n varH = (∑ f1log2 f1 –(∑ f1log f1)2 / n) / n2 t = H1 – H2 / (√ var H1 + var H2 ) *t – to determine if two values you obtain for the index are significantly different you can use the ttest df = (varH1 + var H2 )2
