Answer 1

Нет.

Data Analysis of Sociological Survey Results

Based on the provided data, the results of the sociological survey are as follows: - Number of respondents: 2000 - Number of respondents who like ice cream: 1648 - Number of respondents who like pastries: 1215 - Number of respondents who like both ice cream and pastries: 847

Verification of Survey Results

The accuracy of the survey results can be verified by checking if the numbers add up correctly and if the processing of the data aligns with the principles of set theory.

1. Verification of Total Count: - The total count of respondents liking ice cream or pastries should not exceed the total number of respondents (2000).

2. Verification of Overlapping Preferences: - The number of respondents who like both ice cream and pastries should not exceed the total count of respondents who like ice cream or pastries individually.

Analysis of the Results

Let's verify the accuracy of the survey results based on the provided data.

1. Total Count Verification: - The total count of respondents who like ice cream or pastries is 1648 (ice cream) + 1215 (pastries) - 847 (both) = 2016, which exceeds the total number of respondents (2000). This indicates a discrepancy in the data processing.

2. Overlapping Preferences Verification: - The number of respondents who like both ice cream and pastries (847) is greater than the total count of respondents who like ice cream (1648) or pastries (1215) individually. This also indicates a discrepancy in the data processing.

Conclusion

Based on the provided data, it seems that there are inconsistencies in the processing of the survey results. The total count of respondents who like ice cream or pastries exceeds the total number of respondents, and the count of respondents who like both ice cream and pastries is greater than the total count of respondents who like ice cream or pastries individually.

It is important to review the data processing methods to ensure the accuracy of the survey results.
