Questions

Before completing the following questions, be sure to work through all problems presented in the content. (Note: Data that is necessary to complete this assignment will be entered in the calculator.)

As indicated during the unit, an exponential curve may or may not be the best equation to use to find the vertices of the missing parabolas. In this assignment you will find two other equations, available on the calculator, and then determine which of the three choices provides the “best fit” for the data.

The above process can be repeated a third time using a “PwrReg” (Power Regression) also found on your calculator. (In fact the calculator provides even more possibilities such as using a “QuartReg” (Quartic Regression) or even using a “QuadReg” on the vertices). For the rest of this assignment, we will use a “PwrReg”.

Now that you have performed three regression equations for the “Ping-Pong” data, you should have an indication of which one modeled the data most accurately. Based on your conclusions what are the best answers to the following questions?

10) Which of the following would improve the modeling behavior of all three regression activities?

11) Based on your observations of the changes above in the graph, what is the best statement about the initial condition for the dropped Ping-Pong ball?

a.) The initial condition recorded the height above the floor from which the ball was dropped.

b.) The initial condition recorded the affect of gravity on the ball.

c.) The initial condition recorded that the ball was dropped and not tossed up as the value is positive and a negative value would have meant it was tossed up first.

d.) The initial condition recorded that the ball was tossed up.
