Question

andrey found that the success rate of the conversation that started with \howdy!\ was 20 percent greater than the success rate of the conversation that started with \hiya!\ based on some re-randomization simulations, he concluded that the result is significant and not due to the randomization of the calls.

what valid conclusions can be made from this result?

mark the most suitable choice.

choose 1 answer:

a the result suggests a positive correlation between greeting potential insurance customers with \howdy!\ and the success rates of the calls.

b the result suggests that greeting potential insurance customers with \howdy!\ will likely be more successful than using \hiya!\

c every customer prefers being greeted by \howdy!\ instead of \hiya.\

Explanation:

• Option A: The problem states the success rate of "Howdy!" is 20% greater than "Hiya!", but "correlation" implies a relationship that might not be directly causal or about the greeting type's effect on success rate in the way this option frames it. The key here is the comparison of success rates between the two greetings.
• Option B: Since the success rate of "Howdy!" is 20% greater and the result is significant (not due to randomization), it is reasonable to conclude that using "Howdy!" is likely more successful than "Hiya!" for greeting potential insurance customers.
• Option C: The statement "every customer" is an overgeneralization. The data is about success rates of conversations, not individual customer preferences, and a 20% greater success rate does not mean all customers prefer "Howdy!".

Answer:

B. The result suggests that greeting potential insurance customers with "Howdy!" will likely be more successful than using "Hiya!"
