 A gas utility analyzed temperature data (X) and natural gas consumption

A gas utility analyzed temperature data (X) and natural gas consumption measured in therms (Y) for 8 data points from prior years. Using the summarized information below, calculate the correlation between temperature and therms, the coefficient of determination, the standard error of the regression and the t calculated you would get from a hypothesis test with a null stating the true population slope equals zero. The sum of X = 510.2000 The sum of each X value after squaring them = 36,837.8800 The sum of Y = 228.6800 The sum of each Y value after squaring them = 7,533.5240 The sum of each X multiplied by its corresponding Y (sum([xy]) = 12,774.1770 SSxx = 4,299.8750, SSyy = 996.7062, SSxy = -1,809.8900 correlation = 6.2569, coefficient of determination = 0.0954, standard error of the regression = 234.8929, t calculated = -3.0879 correlation = 0.7643, coefficient of determination - -0.8743, standard error of the regression = 6.2569, t calculated - -4.4113 correlation = 0.7643, coefficient of determination - -0.8743, standard error of the regression = 234.8929, t calculated = -5.2935 correlation - -0.8743, coefficient of determination - 0.7643, standard error of the regression = 6.2569, t calculated - -4.4113 correlation = -0.8743, coefficient of determination = 0.7643, standard error of the regression = 0.0954, t calculated - -4.4113
