Given the information and formula below, how would I calculate the vectors z1,z2,z3,z4?

The image above shows a dataset of two dimensions: 31 - 20, -5 32 - 82 2: - -63 ,2. - 6, -13 The mean vector u of the data set is: And the covariance C is: 85 21.5 C - -24.5 12.5 0.133 0.096 10.096 0.418 4. [2 points] Whitening Please applying whitening to the dataset. Recall, the formula of whitening is What are the resulting vectors { zhi = = = }
