You are standing in Top of a building that is under construction. Someone Drops a box of nails off the
side of the building, and you count that it takes at least 5 seconds for the box
to hit the ground. The time
it takes something to fall from a distance d (in meters)can be found from the equation
A. using this equation, Figure out the range of possible heights the building has.
B. Later in the day you decide to try a more precise experiment. You stand at a differnt height in the building and Drops the box of nails, but this time you use a stopwatch. You measure that it took exactly 3.4 seconds for the nails to hit the ground. How high were you when you dropped the nails?

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.
