Homework 5 Part A

Homework 5 (part a): 40 pointsFind the first and second principal components for the following data set following steps 1through 4 given on the paper “A tutorial on Principal Components Analysis” by Lindsay I Smith.What is the percentage of variance explained by each principal components? Plot the twoprincipal components along with the mean subtracted data you get in step 2.

Note: Please calculate the value of eigenvalue and eigenvector in step 4 manually by hand. For other steps, you ‘can’ use Excel or MATLAB but it is not mandatory.

I’ve attached the data points
