The answer is

If we put 36x^2, then the answer we would get is

Hope this helps :)
I can only see a white picture
The statement " only the estimate intercept is statistically significant at the 5% level is wrong" is wrong about the estimate.
<h3>What is probit regression?</h3>
A probit model is a type of regression in statistics where the dependant variable can only take two values.
We have:
Regress smoker on cubic polynomials of age
If we use linear probability model.
Here the data are missing, but we can say about the estimate that:
Only the estimate intercept is statistically significant at the 5% level is wrong,
Thus, the statement " only the estimate intercept is statistically significant at the 5% level is wrong" is wrong about the estimate.

The inverse is:

Further explanation:
Given function

<u>Step 1: Replacing f(x) with y</u>

<u>Step 2: Replacing x with y and y with x</u>

<u>Step 3: Solving the equation for y</u>

<u>Step 4: Replacing y with f-1(x)</u>

So, the inverse is:
