Step 1 :Calculate the mean of carbohydrates and energy. Mean of carbohydrates = \(\frac{9.5 + 8 + 3 + 6 + 9 + 5}{6} = 6.75\) grams. Mean of energy = \(\frac{29 + 37 + 26 + 13 + 28 + 24}{6} = 26.17\) kilocalories.
Step 2 :Calculate the standard deviation of carbohydrates and energy. Standard deviation of carbohydrates = \(\sqrt{\frac{(9.5-6.75)^2 + (8-6.75)^2 + (3-6.75)^2 + (6-6.75)^2 + (9-6.75)^2 + (5-6.75)^2}{5}} = 2.22\) grams. Standard deviation of energy = \(\sqrt{\frac{(29-26.17)^2 + (37-26.17)^2 + (26-26.17)^2 + (13-26.17)^2 + (28-26.17)^2 + (24-26.17)^2}{5}} = 7.77\) kilocalories.
Step 3 :Calculate the covariance of carbohydrates and energy. Covariance = \(\frac{(9.5-6.75)*(29-26.17) + (8-6.75)*(37-26.17) + (3-6.75)*(26-26.17) + (6-6.75)*(13-26.17) + (9-6.75)*(28-26.17) + (5-6.75)*(24-26.17)}{5} = 4.65\).
Step 4 :Calculate the correlation coefficient. Correlation coefficient, r = \(\frac{Covariance}{Standard deviation of carbohydrates * Standard deviation of energy} = \frac{4.65}{2.22 * 7.77} = 0.269\).
Step 5 :\(\boxed{So, the correlation coefficient between the amount of carbohydrates and the energy provided is r = 0.269.}\)
