In a study conducted to examine the quality of fish after 7 days in ice storage, tên raw fish of the same kind and approXximately the same size were caught and prepared for ice storage. The fish were placed in ice storage at different times after being caught. A measure of fish quality was given to each fish after 7 days in ice storage. Review the accompanying sample data and scatterplot, where "Time" is the number of hours after being caught that the fish was placed in ice storage and "Fish Quality" is the measure given to each fish after 7 days in ice storage (higher numbers mean better quality). Is it appropriate to use the correlation coefficient to describe the strength of the relationship between "Time" and "Fish Quality"? Click the icon to view the sample data and the corresponding scatterplot. ..... Choose the correct answer below. O A. No, because "Fish Quality" is not quantitative. O B. No, because there are a couple of influential outliers. O C. Yes, because both variables are quantitative and there is a linear relationship between the two variables. O D. No, because there is very little scatter of the points around a line fit between the points.

Question
In a study conducted to examine the quality of fish after 7 days in ice storage, ten raw fish of the same kind and approximately the same size were caught and prepared for ice storage. The fish were placed in ice storage at different times after being caught. A measure of fish quality was given to each fish after 7 days in ice storage. Review the accompanying sample data and scatterplot, where "Time" is the number of hours after being caught that the fish was placed in ice storage, and "Fish Quality" is the measure given to each fish after 7 days in ice storage (higher numbers mean better quality). Is it appropriate to use the correlation coefficient to describe the strength of the relationship between "Time" and "Fish Quality"? Choose the correct answer below. A. No, because "Fish Quality" is not quantitative. B. No, because there are a couple of influential outliers. C. Yes, because both variables are quantitative and there is a linear relationship between the two variables. D. No, because there is very little scatter of the points around a line fit between the points. --- **Data table and scatterplot:** - **Data Table:** | Time (hours) | Fish Quality | |--------------|--------------| | 0 | 8.5 | | 2 | 8.4 | | 3 | 8.0 | | 5 | 8.1 | | 6 | 7.8 | | 7 | 7.6 | | 9 | 7.3 | | 11 | 7.0 | | 12 | 6.8 | | 13 | 6.7 | - **Scatterplot Explanation:** The scatterplot displays "Time" on the x-axis (in hours) and "Fish Quality" on the y-axis. Each data point is represented by a blue dot, showing the relationship between the time the fish were placed in storage and their quality after 7 days. The scatterplot reveals a downward trend, indicating that as the time before storage increases, the fish quality decreases, suggesting a linear relationship between the two variables.
