Solution
To find the correct column, we need to calculate the percentage of each response from the total number of respondents.
- "The most important thing" - 10 out of 1033 is approximately 0.97%, which is closest to 1%.
- "Very important" - 145 out of 1033 is approximately 14.03%, which is closest to 14%.
- "Somewhat important" - 434 out of 1033 is approximately 42.01%, which is closest to 42%.
- "Not too important" - 320 out of 1033 is approximately 30.98%, which is closest to 31%.
- "Not at all important" - 124 out of 1033 is approximately 12%, which is closest to 12%.
So, the correct column is Column C.
