r <br />Table 3. Population estimate (N) for roundtail chub adults (>200 mm) in Westwater Canyon 1998- <br />2000. Population estimate generated using the null estimator (Mo) within program <br />~ CAPTURE. The profile likelihood interval, coefficient of variation (CV), and probability <br />of capture (p-hat) are included with the respective population estimates. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />Year N Profale Likelihood <br />Interval CV p-hat <br />1998 5,005 3,586-19,781 0.30 0.026 <br />1999 4,234 -- 3,349-12,917 0.23 0.037 <br />2000 4,971 3,824-16,641 0.25 0.031 <br />Table 4.
