Problem 2 Given two lists x and y, return the correlation coefficient between x and y rounded to 2 decimal places. The correlation coefficient is defined as: r= (Xi ) (yi -T) ( (xi )? (yi ) Note: To compute the square root of a number x, import math library, then use math.sqrt(x) Hint: compute each component(each one of the summations) seperately, and then combine them to get r.
