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, scatterplot, and Minitab output from a simple linear regression analysis, 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). What percentage of the variation in "Fish Quality" is accounted by this linear regression model with "Time" as the explanatory variable?

R-sq denotes percentage of the variation in "Fish Quality" is accounted by this linear regression model with "Time" as the explanatory variable. From the output, R-sq = 98.1%.
The correct answer is:
B. 98.1%
