Question:

Given 20 data points in 2-D space whose first principal component is $u=\left(\frac{1}{\sqrt{2}}, \frac{1}{\sqrt{2}}ight)^{\prime}$.

a. Suppose we add one more data point at $(2,2)^{\prime}$; how would that affect the first principal component?

b. Suppose we add one more data point at $(3,0)^{\prime}$; how would that affect the first principal component?

c. Suppose we add an infinite number of data points at $(5,0)^{\prime}$; how would that affect the first principal component?
