Write the function rsq(x, y) that takes as parameters two lists of values, and calculates and returns the square of the correlation between those two data series, which is a measure of the goodness of fit measure to explain variation in y as a function of variation of x. >>> X = [4,4,3,6,7] >>> y = >>> rsq(x,y) 0.9831154684095857 [6,7,5,10,12] Additional Example: we expect no correlation and very low r-square between randomly selected data values. This test uses two lists of random numbers. Notice the very low r- squared. >>> import random >>> a = list(range(30)) >>> b = list (range(30)) >>> random.shuffle(a) >>> random.shuffle(b) >>> a [6, 24, 29, 8, 20, 7, 28, 23, 14, 11, 25, 19, 12, 17, 2, 0, 26, 9, 10, 1 >>> b [17, 22, 25, 29, 27, 7, 11, 19, 26, 16, 0, 9, 21, 18, 3, 24, 8, 10, 20, >>> correlation(a,b) 0.12880978865406006 >>> rsq(a,b) 0.016591961653103622
