The gypsy moth is a serious threat to oak and aspen trees. a state agriculture department places traps throughout the state to detect the moths. when traps are checked periodically, the mean number of moths per trap is only 1.2, but some traps have several moths. the distribution of moth counts in traps is strongly right skewed, with standard deviation 1.4. a random sample of 60 traps has x = 1 and s = 2.4.
let x = the number of moths in a randomly selectd trap
(a) for the population distribution, what is the
? =
deviation? =
(b) for the distribution of the sample data, what is the
? =
deviation? =

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.
