2. 4) What is the difference between the standard deviation and the standard error of an estimate (4 pts). _________________________________________________ _________________________________________________ ________________________________________________. 5) 100 fish are caught, marked and released in a small farm pond. One week later, a second capture effort was made and results in 20 fish being caught, of which 5 were marked. What is the most likely number of fish in the pond. Assume all mark- recapture assumptions were met. (5 pts). ___________. 6)In question 5, if the population was not a closed would you (circle one, 4 pts); a) overestimate the population, b) underestimate the population, c) have no effect, or d) could have undeterminable effects. 7)In question 5, if the marked fish lost their marks would you (circle one. 4 pts); a) overestimate the population, b) underestimate the population, c) have no effect, or d) could have any either effect. 8)Is this equation considered the null hypothesis or the alternative hypothesis in standard statistical methods? (2 points, circle one) Null Alternative. 9) In management situations is the null hypotheses likely to be exactly true? (2 pts, circle one) Yes No. 10) A type I statistical error is accepting the null hypothesis when the hypotheses is in reality (2 pts, circle one). True False

Pass 1 Pass 2 Pass 3 12) In thirty words or less define the term stock as it was used in this class (6 pts). _______________________________________________ _______________________________________________ _______________________________________________ _______________________________________________ _______________________________________________ ______________________________________________. 13) Which of the following terms describes the number of chromosome a fish has? (3 points – circle one) A) Gene B) Locus C) Allele D) Karyotype

4. 14) Assume the following fish scale was aged correctly and measured accurately. Lines on the scale indicate age and distance from focus. When this scale was removed at age 4+, the fish was 50 inches long. Based on the data presented how long was the fish when it was age 1 (6 pts). ________inches. Age 0, 0 μm Age 1, 20 μm Age 2, 100 μm Age 3, 150 μm Age 4, 180 μm Age 4+, 200 μm 15) In fisheries a common evaluation tool is statistical significance. Even if a result is not statistically significant is may still be of ____________ significance. (4 pts, fill in the blank)
