Final answer:
The hypothesis in the statement 'If Rita is playing a CD, then Ravi is dancing' is 'Rita is playing a CD', which is the condition leading to the outcome stated in the conclusion.
Step-by-step explanation:
In the conditional statement 'If Rita is playing a CD, then Ravi is dancing', the hypothesis is the part that follows the 'If', which is 'Rita is playing a CD'. This is because in a conditional statement, also known as an if-then statement, the hypothesis is the assumption that can be tested. It's the condition that leads to the 'then' part of the statement, known as the conclusion.
