NOTE: Please show me STEPS how to resolve these two questions in "STATCRUNCH" Question1) 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 of students in a large class is than . A simple random sample of the students has a mean of 97.3. 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 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 not sufficient evidence to support the claim. Question 2) Assume a significance level of α=0.05 and use the given information to complete parts (a) and (b) below. Original claim: Less than 41% of adults would erase all of their personal information online if they could. The hypothesis test results in a P-value of 0.2557. a. State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0.) Choose the correct answer below: A. Fail to reject H0 because the P-value is greater than α. B. Fail to reject H0 because the P-value is less than or equal to α. C. Reject H0 because the P-value is greater than α. D. Reject H0 because the P-value is less than or equal to α.

Question1)
Make a decision about the given claim. Use only the rare
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 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 not sufficient evidence to support the claim.
Question 2)
Assume a significance level of α=0.05 and use the given information to complete parts (a) and (b) below. Original claim: Less than 41% of adults would erase all of their personal information online if they could. The hypothesis test results in a P-value of 0.2557.
a. State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0.)
Choose the correct answer below:
A. Fail to reject H0 because the P-value is greater than α.
B. Fail to reject H0 because the P-value is less than or equal to α.
C. Reject H0 because the P-value is greater than α.
D. Reject H0 because the P-value is less than or equal to α.
