$1.$Calculate, interpret and compare the coefficient of variation of the three companies and the portfolio. In this answer you should include the section of your R code that allows you to do the computation.

$2.$Comment and compare the linear relationship between each of the three companies versus the portfolio based on the Covariance and Correlation measures. Your response should include: interpretation of each measure and distinction between the two measures.

$3.$Calculate and interpret the linear relationship between the companies using the correlation coefficient. Here you need to calculate the correlation between company pairs. For example: company $1$ vs company $2,$ company $1$ vs company $3,$ etc. In this answer you should include the section of your R code that allows you to do the computation.

$4.$Discuss and compare the correlation results in questions $2$ and $3$ above.
