Question

Please help!!!
Very urgent, which of these models would best represent the data and why?

Answer 1

Hey !

Given,

The height of the rocket is recorded at different times and 3 regression models are shown, which are f(x) , g(x), h(x)

As per the values,

At t= 1; Height of the Rocket is 10 ft.

But this is not TRUE for f(x), since it shows height as negative, which is not possible.

•°• Exclude f(x) from the options.



Left with g(x) and h(x)

At t= 5; Height of the Rocket is 1200 ft.

But this is not TRUE for g(x) as it is nearer/equal to 2000 at t=5.

And at t = 5,

h(x) is nearer to /equal to 1200.

Also other values of h(x), are much representing the best as per the recorded table data given.

The exact graph for the given values is shown in the attachment.

•°• h(x) is representing the best of all 3 regression models.


Kind Note: The graph taken is neither from text book nor from other sources of Internet, its just a plot made using a tool.
