Objective #4: Consider the data matrices X and Y, both at in Objective #3. X contains the Old Faithful dataset, and Y is the centered version/variant of X. With X and Y in mind, please answer the following questions and include the answers in your submitted PDF document: Q1. Write a matrix P that, when multiplied by X (i.e., XP), will produce a new data matrix where all values of "eruption duration" (currently in minutes) are in seconds, and where all values of "time to next eruption" (currently in minutes) are in hours. Q2. The covariance matrix of data matrix X is: 1.29 13.87 x 13 183.54 Write the covariance matrix (i.e., Kyy) of the centered data matrix Y. Q3. Write a matrix that, when multiplied by the covariance matrix of X (i.e., QKxx), will produce the identity matrix.
