L = 17 + 2.4M One end of a rubber band is stapled to the bottom of a table. When
an object of mass M kilograms is attached to the other end of the
rubber band, the rubber band stretches to a length of L centimeters
as shown in the equation above. What is M when L = 29 ?

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.
