Water and Carbohydrates Here are the number of grams of water and the number of grams of carbohydrates for a random selection of raw foods (100 g each). Is there a linear relationship between the variables? Water 85.54 85.28 87.11 74.45 84.74 83.83 73.16 Carbs 21.44 11.81 21.68 14.03 17.35 22.63 15.78 1) Compute the value of the correlation. Round your answer to at least 3 decimal places. r = ___ 2) State the hypothesis H0: H1: 3) Test the significance of the correlation coefficient at a= 0.05 a) critical values? +/- ____ b) Give a brief explaination of the type of relationship? There (IS or IS NOT) a significant linear realtionship between the number of grams of water and the number of grams of carbohydrates.
