To estimate the number of trout in a lake, we caught 40 trout, tagged and returned them. Later we caught 40 trout and found that three of them were tagged. From this experiment, estimate n, the number of trout in the lake. Hint: Let pn be the probability of three tagged trout among the second 40 caught. Find the value of n that maximizes pn.

17. a researcher measures three variables, x, y, and z for each individual in a sample of n = 20. the pearson correlations for this sample are rxy = 0.6, rxz = 0.4, and ryz = 0.7. a. find the partial correlation between x and y, holding z constant. b. find the partial correlation between x and z, holding y constant. (hint: simply switch the labels for the variables y and z to correspond with the labels in the equation.) gravetter, frederick j. statistics for the behavioral sciences (p. 526). cengage learning. kindle edition.
