Extracted text: 2. Accidentally a Scientist discovered "Sesame" during his research and he observed that 12.0 quintals per acre yield can be expected by sowing the seeds. To verify his expectation, he put request to 10 farmers who are nearby his research center and they agreed. Seeds were sowed and the yield came after few months. The yields (quintals/acre) were recorded as 14.3, 12.6, 13.7, 10.9, 13.7, 12.0, 11.4, 12.0, 12.6, 13.1. Do the results confirm the expectation with 95% confidence?
