a) Doternine the correlation coefficient between the amount of carbohydrates and the energy provided

The correlation coefficient between the amount of carbohydrates and the energv provided is $r=\square$
(Type an integer or decimal rounded to three decimal places as needed)
b) Determine whether a correlation exists at $\alpha=0.05$ Choose the correct answer below
A linear correlation does not exist.
A linear correlation exists

Step 1 ：The correlation coefficient, often denoted by r, measures the strength and direction of a linear relationship between two variables. In this case, we are asked to find the correlation coefficient between the amount of carbohydrates and the energy provided.

Step 2 ：Given the carbohydrates values as [7.5, 9, 1, 2, 7, 7] and energy values as [23, 33, 24, 13, 22, 32].

Step 3 ：Calculate the correlation coefficient, r, between these two sets of values.

Step 4 ：The calculated correlation coefficient, r, is approximately 0.641. This value is between 0.5 and 1, indicating a moderate positive correlation between the amount of carbohydrates and the energy provided.

Step 5 ：This means that as the amount of carbohydrates increases, the energy provided also tends to increase. However, this is not a strong correlation, so there may be other factors at play.

Step 6 ：Final Answer: The correlation coefficient between the amount of carbohydrates and the energy provided is \( \boxed{0.641} \).
