Question: A firm has £120,000 to invest. It can buy shares in company X which cost £2 each and give an expected annual return of 6%, or shares in company Y which cost £4 each and give an expected annual return of 8%. It is advised not to put more than 60% of its total investments into any one type of share. What investment portfolio will maximize the expected return? (You may answer this question with or without a diagram.)

Assuming Raoult's Law to be valid, prepare a Txy diagram for a mixture n-butane (1) and n-hexane (2) at 1 atm. Make the plot in terms of n-butane and be sure to clearly label the bubble line and the dew line. Use the following increments for T:
These are the results of running 5-fold cross-validation on each of the ridge and lasso models, and using the usual rule (min) or the one-standard-error rule (1se) to select λ. How do the coefficient estimates from the usual rule compare to those ..
