Using the data inspector. Record some values for the height of
the projectile as a function of time. Using these data and any
graphical analysis program you like, create a graph of projectile
height as a function of time and generate a quadratic fit to your
data.
My data is as follows:
(time, height): (0.1s,1.25m), (0.3s, 3.46m), (0.6s, 6.03m),
(0.8s, 7.25m), (1.1s, 8.35m), (1.3s, 8.6m), (1.5s, 8.45m), (1.8s,
7.49m), (2.2s, 4.84m), (2.6s, 0.62m)
Initial: angle- 60 degrees, speed, 15 m/s,...

Provide an interpretation of your regression results.
You should include the goodness of fit, the F-stat, and the signs
and significance of the estimated coefficients in your discussion.
Remember that if P-values are small Excel will report them in
scientific notation.

this data, what proportion of observed variation in maximum
prevalence could be explained by the model relationship? (Round
your answer to three decimal places.)
