Q$11.$ Create a new matrix zmale being a version of the male dataset with each of its eight columns standardised $($by computing the z$-$scores of each column$).$

$5$

Q$12.$ Perform the aforementioned subtasks Q$8$Q$10$ on zmale instead of on the original male dataset $($do

not include two pairplots nor four heatmaps$).$

Note that the pairplot will look exactly like above, but with different ranges on the x$-$ and y$-$axes

$($ca$.$ from $-3$ to $3,$ but maybe a bit less$/$more sometimes$).$ The correlation coefficients$$ values will

be exactly the same as in the undergraduate version, because standardisation only involves the

shifting and scaling of data
