We would expect six or seven measurements (roughly seven) to fall within the range because of the
68.27%. In reality seven of the 10 values fall into the range of standard deviation. (86, 85, 84, 85, 87, 85,

1. Since the ruler starts at rest and one can set its initial height at zero, the first two parts of the
equation can be set to zero: y(t) = yi +vit (1/2) gt^2
y(t) = 0 + 0 (1/2)gt^2 = -1/2(g)t^2
Thus, solving for t (time) in
