1. Data below shows time (s) after a ball was thrown up in the air vs. its height (m).

T	0.0 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 1.8
H	0.0 1.7 3.1 3.9 4.5 4.7 4.6 4.1 3.3 2.1

A. Calculate r. At a=0.05, determine if there is significant linear correlation.

B. If there is significant linear correlation, find the regression line. If not, skip this step.

C. Predict the height of the ball after 1.1 sec
