A random sample of 10 subjects have weights with a standard deviation of 11.7485 kg. What is the variance of their weights? Be sure to include the appropriate units with the result. The variance of the sample data is
(Round to four decimal places as needed.)

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.
