Question

How can I compute the interpolating polynomial p ∈ P5 that interpolates the values (ti, yi) and estimate the population of New Zeland for all the years between 1991 and 2016 using cubic spline (in Python).

where
Consider the following array:
t
Y
1991
1996
2001
2006
3,516,000 3,762, 300 3,916, 200 4, 209, 100
Yi is the population of New Zealand in the year t;.
2011
4, 399, 400
2016
4,747, 200

Expert Solution
Step 1

As per the question we have to write a program to calculate estimated population using newinterp function in python.
In step 2, we write a program to calculate the estimated population using the newinterp function.
Let's start with step 2.
Note: According to the question, we only have to solve part a. thus providing the solution to part a.

Follow-up Question

How do I use cubic spline to solve this question? And how do I get an estimate for all the years between 1991 until 2016 (not only an overall estimate).
