Table 4. Bonferonni intervals for the presence, transience, and absence of cheetahs in areas deemed suitable and unsuitable for cheetahs in Botswana (k = 4, α = 0.05, Z = 2.4977).
The proportion of farmers that reported cheetahs present or absent differed significantly between suitable and unsuitable areas (χ2 = 129.11, df = 3, P < 0.001). Data were based on questionnaires completed by game ranchers and commercial livestock farmers (N = 89) during 2012 and 2013 in the game ranching regions of the Central, Ghanzi, Ngamiland and North East regional districts (Boast, 2014). Simultaneous confidence intervals for the presence, transience, and absence of cheetahs based on questionnaires completed by farmers (N = 89) in areas deemed suitable and unsuitable for cheetahs in Botswana (k = 4, α = 0.05, Z = 2.4977).
