Make a decision about the given claim. Use only the rare event​ rule, and make subjective estimates to determine whether events are likely. For​ example, if the claim is that a coin favors heads and sample results consist of 11 heads in 20​ flips, conclude that there is not sufficient evidence to support the claim that the coin favors heads​ (because it is easy to get 11 heads in 20 flips by chance with a fair​ coin). ​Claim: The mean respiration rate (in breaths per minute) of students in a large calculus class is greater than 15. A simple random sample of the students has a mean respiration rate of 29.5. Choose the correct answer below. A. The sample is unusual if the claim is true. The sample is not unusual if the claim is false.​ Therefore, there is sufficient evidence to support the claim. B. The sample is unusual if the claim is true. The sample is not unusual if the claim is false.​ Therefore, there is not sufficient evidence to support the claim. C. The sample is not unusual if the claim is true. The sample is unusual if the claim is false.​ Therefore, there is sufficient evidence to support the claim. D. The sample is not unusual if the claim is true. The sample is unusual if the claim is false.​ Therefore, there is not sufficient evidence to support the claim.
