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 left parenthesis in breaths per minute right parenthesis of students in a large calculus class is greater than12.

A simple random sample of the students has a mean respiration rate of 31.6.

  • Choose the correct answer below.
  • A. 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.
  • 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 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.
  • D. 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.

Claim: The mean respiration rate (in breaths per minute) of students in a large calculus class is greater than 12. A simple random sample of the students has a mean respiration rate of 31.6.
Choose the correct answer below.
O A. 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.
O 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.
O C. 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.
O D. 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.
