We are given 6 observations with the following sums: [ \sum X_i = 30, \quad \sum Y_i = 180, \quad \sum X_i Y_i = 1000, \quad \sum X_i^2 = 200, \quad \sum Y_i^2 = 5642 ] Number of observations: ( n = 6 ). Step 1: Compute the means of X and Y. [ \bar{X} = \frac{\sum X_i}{n} = \frac{30}{6} = 5 ] [ \bar{Y} = \frac{\sum Y_i}{n} = \frac{180}{6} = 30 ] Step 2: Compute the correlation coefficient ( r ). The formula: [ r = \frac{n\sum X_iY_i __________ ___ ______ ________ _________ __________ __________.
