Water and Carbohydrates There are many interesting relationships among the various nutrients found in fruits and vegetables. Listed below are the number of grams of water and the number of grams of carbohydrates for a random selection of raw foods ( 100 g each). Water 74.69, 81.33, 79.42, 77.37, 77.87, 73.70, 85.47 Carbs 23.36, 16.65, 20.64, 20.33, 21.73, 23.35, 16.85 The correlation coefficient for the data is r= -.920 and a= .05. Should regression analysis be done? The regression analysis should not be done or The regression analysis should be done. Find the equation of the regression line. Round the coefficients to at least three decimal places, if necessary y'= a+bx a= b= find y' when x= 78. Round the answer to at least three decimal places, if necessary y'=
