a. Determine the coefficient of determination, \( r^2 \), and interpret its meaning.
\[ r^2 = 0.9456 \] (Round to four decimal places as needed.)
Interpret the meaning of \( r^2 \).
It means that \(\_\_\_\_\) % of the variation in the cost of a meal \(\_\_\_\_\) be explained by the variation in summated ratings. (Round to two decimal places as needed.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F710e59c6-4738-4995-a68d-52cf2fbdc504%2F40a4c83f-d70d-4650-97eb-6bd602da63f6%2Futabppa_processed.png&w=3840&q=75)
