Ridge regression: Write some code which perform L2 regularization. That is, solve OLS with a constraint that the L2 norm of the betas is less than some threshold value. min β Xn i=1 e 2 i subject to Xr i=1 β 2 i ≤ T

Assume that minutes is an int variable whose value is 0 or positive. write an expression whose value is "undercooked" or "soft-boiled" or "medium-boiled" or "hard-boiled" or "overcooked" based on the value of minutes. in particular: if the value of minutes is less than 2 the expression's value is "undercooked"; 2-4 would be a "soft-boiled", 5-7 would be "medium-boiled", 8-11 would be "hard-boiled" and 12 or more would be a "overcooked".
