A study determined the hоme rаnge size (аcres) оf mоose living in Cook аnd Lake counties in Minnesota (the arrowhead region). Home range size for bull moose in Cook County had a mean of 19 square miles (95% Confidence Interval of 14-24 square miles). Home range size for bull moose in Lake County had a mean of 15 square miles (95% CI of 12-18 square miles). The means are different, but the confidence intervals substantially overlap (14-18 square miles). If we read further in the study and they compare these 2 populations with a statistical test, at the same alpha level, with the Ho: There is no difference in the home range size of bull moose in Lake and Cook Counties; how likely is it that they will find a statistically significant difference in home range size?
