Describe in your own words the hypothesis being tested in the 1 1=2 vs. 1 1=3 experiment, the procedure used, the result, and the interpretation of the result.
a. The hypothesis being tested is whether participants perceive the equality of two different mathematical expressions (1 + 1 = 2 vs. 1 + 1 = 3). The procedure involved presenting participants with both expressions and asking them to indicate whether they are equal or not. The result showed that a significant portion of participants incorrectly perceived 1 + 1 = 3 as equal. The interpretation suggests a cognitive bias or misconception in mathematical reasoning.
