Q) The following 3 by 2 matrix contains data on two continuous variables for three individuals:

X = 3 4

5 9

2 5

Define and calculate thesum of squares and cross products matrix, and calculate the associated covariance matrix.

My A)

the sum of squares and cross products is given by X(transpose)*X which gives me

25 51 26

51 106 55

26 55 29

how can we get the covariance matrix from this new matrix as the question is only worth 3 marks and im guessing we have to use this new matrix?
